List of Chromium Command Line Switches

There are lots of command lines which can be used with the Google Chrome browser. Some change behavior of features, others are for debugging or experimenting. This page lists the available switches including their conditions and descriptions. Last automated update occurred on 2018-10-20.

Condition	Explanation
--	Report pseudo allocation traces. Pseudo traces are derived from currently active trace events.
--/prefetch:1	/prefetch:# arguments to use when launching various process types. It has been observed that when file reads are consistent for 3 process launches with the same /prefetch:# argument, the Windows prefetcher starts issuing reads in batch at process launch. Because reads depend on the process type, the prefetcher wouldn't be able to observe consistent reads if no /prefetch:# arguments were used. Note that the browser process has no /prefetch:# argument; as such all other processes must have one in order to avoid polluting its profile. Note: # must always be in [1, 8]; otherwise it is ignored by the Windows prefetcher.
--/prefetch:2	No description
--/prefetch:3	No description
--/prefetch:4	No description
--/prefetch:5	/prefetch:# arguments for the browser process launched in background mode and for the watcher process. Use profiles 5, 6 and 7 as documented on kPrefetchArgument* in content_switches.cc.
--/prefetch:6	No description
--/prefetch:8	Prefetch arguments are used by the Windows prefetcher to disambiguate different execution modes (i.e. process types) of the same executable image so that different types of processes don't trample each others' prefetch behavior. Legal values are integers in the range [1, 8]. We reserve 8 to mean "whatever", and this will ultimately lead to processes with /prefetch:8 having inconsistent behavior thus disabling prefetch in practice. TODO(rockot): Make it possible for embedders to override this argument on a per-service basis.
--0	Value of the --profiler-timing flag that will disable timing information for chrome://profiler.
--?	No description
--accept-resource-provider	Flag indicating that a resource provider must be set up to provide cast receiver with resources. Apps cannot start until provided resources. This flag implies --alsa-check-close-timeout=0.
--account-consistency	Command line flag for enabling account consistency. Default mode is disabled. Mirror is a legacy mode in which Google accounts are always addded to Chrome, and Chrome then adds them to the Google authentication cookies. Dice is a new experiment in which Chrome is aware of the accounts in the Google authentication cookies.
--adaboost	No description
--aec-refined-adaptive-filter	Enables a new tuning of the WebRTC Acoustic Echo Canceler (AEC). The new tuning aims at resolving two issues with the AEC: https://bugs.chromium.org/p/webrtc/issues/detail?id=5777 https://bugs.chromium.org/p/webrtc/issues/detail?id=5778 TODO(hlundin): Remove this switch when experimentation is over; crbug.com/603821.
--agc-startup-min-volume	Override the default minimum starting volume of the Automatic Gain Control algorithm in WebRTC used with audio tracks from getUserMedia. The valid range is 12-255. Values outside that range will be clamped to the lowest or highest valid value inside WebRTC. TODO(tommi): Remove this switch when crbug.com/555577 is fixed.
--aggressive	No description
--aggressive-cache-discard	No description
--aggressive-tab-discard	No description
--all	No description
--allarticles	No description
--allow-cross-origin-auth-prompt	Allows third-party content included on a page to prompt for a HTTP basic auth username/password pair.
--allow-external-pages	Allow access to external pages during layout tests.
--allow-failed-policy-fetch-for-test	If this flag is passed, failed policy fetches will not cause profile initialization to fail. This is useful for tests because it means that tests don't have to mock out the policy infrastructure.
--allow-file-access-from-files	By default, file:// URIs cannot read other file:// URIs. This is an override for developers who need the old behavior for testing.
--allow-hidden-media-playback	Allows media playback for hidden WebContents
--allow-http-background-page	Allows non-https URL for background_page for hosted apps.
--allow-http-screen-capture	Allow non-secure origins to use the screen capture API and the desktopCapture extension API.

--allow-nacl-file-handle-api	Specifies comma-separated list of extension ids or hosts to grant access to file handle APIs.
--allow-nacl-socket-api	Specifies comma-separated list of extension ids or hosts to grant access to TCP/UDP socket APIs.
--allow-no-sandbox-job	Enables the sandboxed processes to run without a job object assigned to them. This flag is required to allow Chrome to run in RemoteApps or Citrix. This flag can reduce the security of the sandboxed processes and allow them to do certain API calls like shut down Windows or access the clipboard. Also we lose the chance to kill some processes until the outer job that owns them finishes.
--allow-outdated-plugins	Don't block outdated plugins.
--allow-ra-in-dev-mode	Allows remote attestation (RA) in dev mode for testing purpose. Usually RA is disabled in dev mode because it will always fail. However, there are cases in testing where we do want to go through the permission flow even in dev mode. This can be enabled by this flag.
--allow-running-insecure-content	By default, an https page cannot run JavaScript, CSS or plugins from http URLs. This provides an override to get the old insecure behavior.
--allow-sandbox-debugging	Allows debugging of sandboxed processes (see zygote_main_linux.cc).
--allow-silent-push	Allows Web Push notifications that do not show a notification.
--alsa-check-close-timeout	Time in ms to wait before closing the PCM handle when no more mixer inputs remain. Assumed to be 0 if --accept-resource-provider is present.

--alsa-output-avail-min	Minimum number of available frames for scheduling a transfer.
--alsa-output-buffer-size	Size of the ALSA output buffer in frames. This directly sets the latency of the output device. Latency can be calculated by multiplying the sample rate by the output buffer size.
--alsa-output-device	The Alsa device to use when opening an audio stream.
--alsa-output-period-size	Size of the ALSA output period in frames. The period of an ALSA output device determines how many frames elapse between hardware interrupts.
--alsa-output-start-threshold	How many frames need to be in the output buffer before output starts.
--alsa-volume-device-name	Name of the device the volume control mixer should be opened on. Will use the same device as kAlsaOutputDevice and fall back to "default" if kAlsaOutputDevice is not supplied.
--alsa-volume-element-name	Name of the simple mixer control element that the ALSA-based media library should use to control the volume.

--max-untiled-layer-width	No description
--media-cache-size	Forces the maximum disk space to be used by the media cache, in bytes.
--mem-pressure-system-reserved-kb	Some platforms typically have very little 'free' memory, but plenty is available in buffers+cached. For such platforms, configure this amount as the portion of buffers+cached memory that should be treated as unavailable. If this switch is not used, a simple pressure heuristic based purely on free memory will be used.
--memlog	Enables the out-of-process memory logging.
--memory-pressure-off	No description
--memory-pressure-thresholds	The memory pressure threshold selection which is used to decide whether and when a memory pressure event needs to get fired.
--memory-pressure-thresholds-mb	Sets the free memory thresholds below which the system is considered to be under moderate and critical memory pressure. Used in the browser process, and ignored if invalid. Specified as a pair of comma separated integers. See base/win/memory_pressure_monitor.cc for defaults.

--metrics-client-id	This is how the metrics client ID is passed from the browser process to its children. With Crashpad, the metrics client ID is distinct from the crash client ID.
--metrics-recording-only	Enables the recording of metrics reports but disables reporting. In contrast to kDisableMetrics, this executes all the code that a normal client would use for reporting, except the report is dropped rather than sent to the server. This is useful for finding issues in the metrics code during UI and performance tests.
--mhtml-generator-option	Sets options for MHTML generator to skip no-store resources: "skip-nostore-main" - fails to save a page if main frame is 'no-store' "skip-nostore-all" - also skips no-store subresources.

--mse-video-buffer-size-limit	No description
--mus	Used to enable mus as a separate process, but chrome+ash still together.
--mus-config	This is added to child processes launched from mash or mus. The value of this switch is either kMus or kMash. For example, if chrome is run with '--mash' then the child process representing ash is launched with the switch '--mus-config=mash'.
--mute-audio	Mutes audio sent to the audio device so it is not audible during automated testing.
--nacl-broker	Value for --type that causes the process to run as a NativeClient broker (used for launching NaCl loader processes on 64-bit Windows).
--nacl-dangerous-no-sandbox-nonsfi	Disable sandbox even for non SFI mode. This is particularly unsafe as non SFI NaCl heavily relies on the seccomp sandbox.
--nacl-debug-mask	Uses NaCl manifest URL to choose whether NaCl program will be debugged by debug stub. Switch value format: [!]pattern1,pattern2,...,patternN. Each pattern uses the same syntax as patterns in Chrome extension manifest. The only difference is that * scheme matches all schemes instead of matching only http and https. If the value doesn't start with !, a program will be debugged if manifest URL matches any pattern. If the value starts with !, a program will be debugged if manifest URL does not match any pattern.
--nacl-gdb	Native Client GDB debugger that will be launched automatically when needed.
--nacl-gdb-script	GDB script to pass to the nacl-gdb debugger at startup.
--nacl-loader	Value for --type that causes the process to run as a NativeClient loader for SFI mode.
--nacl-loader-nonsfi	Value for --type that causes the process to run as a NativeClient loader for non SFI mode.

It should be present only on devices that have been initially issued with ecrypfs encryption and have ARC (N+) available. For the devices in other categories this flag must be missing.
--net-log-capture-mode	Sets the granularity of events to capture in the network log. The mode can be set to one of the following values: "Default" "IncludeCookiesAndCredentials" "IncludeSocketBytes" See the functions of the corresponding name in net_log_capture_mode.h for a description of their meaning.

--no-default-browser-check	Disables the default browser check. Useful for UI/browser tests where we want to avoid having the default browser info-bar displayed.
--no-experiments	Disables all experiments set on about:flags. Does not disable about:flags itself. Useful if an experiment makes chrome crash at startup: One can start chrome with --no-experiments, disable the problematic lab at about:flags and then restart chrome without this switch again.
--no-first-run	Skip First Run tasks, whether or not it's actually the First Run. Overridden by kForceFirstRun. This does not drop the First Run sentinel and thus doesn't prevent first run from occuring the next time chrome is launched without this flag.
--no-managed-user-acknowledgment-check	Disables checking whether we received an acknowledgment when registering a supervised user. Also disables the timeout during registration that waits for the ack. Useful when debugging against a server that does not support notifications.
--no-network-profile-warning	Whether or not the browser should warn if the profile is on a network share. This flag is only relevant for Windows currently.
--no-pings	Don't send hyperlink auditing pings
--no-proxy-server	Don't use a proxy server, always make direct connections. Overrides any other proxy server flags that are passed.
--no-referrers	Don't send HTTP-Referer headers.
--no-sandbox	Disables the sandbox for all process types that are normally sandboxed.
--no-service-autorun	Disables the service process from adding itself as an autorun process. This does not delete existing autorun registrations, it just prevents the service from registering a new one.
--no-session-id	No description
--no-startup-window	Does not automatically open a browser window on startup (used when launching Chrome for the purpose of hosting background apps).
--no-user-gesture-required	Autoplay policy that does not require any user gesture.
--no-wifi	Disable features that require WiFi management.
--no-zygote	Disables the use of a zygote process for forking child processes. Instead, child processes will be forked and exec'd directly. Note that --no-sandbox should also be used together with this flag because the sandbox needs the zygote to work.
--noerrdialogs	Suppresses all error dialogs when present.
--non-material	Classic, non-material, mode for the
--non-secure	No description
--non-secure-after-editing	No description

--override-plugin-power-saver-for-testing	Override the behavior of plugin throttling for testing. By default the throttler is only enabled for a hard-coded list of plugins. Set the value to 'always' to always throttle every plugin instance. Set the value to 'never' to disable throttling.
--override-use-software-gl-for-tests	Forces the use of software GL instead of hardware gpu.
--overscroll-history-navigation	Controls the behavior of history navigation in response to horizontal overscroll. Set the value to '0' to disable. Set the value to '1' to enable the behavior where pages slide in and out in response to the horizontal overscroll gesture and a screenshot of the target page is shown. Set the value to '2' to enable the simplified overscroll UI where a navigation arrow slides in from the side of the screen in response to the horizontal overscroll gesture. Defaults to '1'.
--overscroll-start-threshold	Controls the value of the threshold to start horizontal overscroll relative to the default value. E.g. set the value to '133' to have the overscroll start threshold be 133% of the default threshold.

--passive-listeners-default	Override the default value for the 'passive' field in javascript addEventListener calls. Values are defined as: 'documentonlytrue' to set the default be true only for document level nodes. 'true' to set the default to be true on all nodes (when not specified). 'forcealltrue' to force the value on all nodes.
--password-store	Specifies which encryption storage backend to use. Possible values are kwallet, kwallet5, gnome, gnome-keyring, gnome-libsecret, basic. Any other value will lead to Chrome detecting the best backend automatically. TODO(crbug.com/571003): Once PasswordStore no longer uses the Keyring or KWallet for storing passwords, rename this flag to stop referencing passwords. Do not rename it sooner, though; developers and testers might rely on it keeping large amounts of testing passwords out of their Keyrings or KWallets.
--permission-request-api-scope	Development flag for permission request API. This flag is needed until the API is finalized. TODO(bauerb): Remove when this flag is not needed anymore.
--permission-request-api-url	Development flag for permission request API. This flag is needed until the API is finalized. TODO(bauerb): Remove when this flag is not needed anymore.

More details here: - http://www.chromium.org/developers/design-documents/process-models - The class comment in site_instance.h, listing the supported process models. IMPORTANT: This isn't to be confused with --site-per-process (which is about isolation, not consolidation). You probably want the other one.
--process-per-tab	Runs each set of script-connected tabs (i.e., a BrowsingInstance) in its own renderer process. We default to using a renderer process for each site instance (i.e., group of pages from the same registered domain with script connections to each other). TODO(creis): This flag is currently a no-op. We should refactor it to avoid "unnecessary" process swaps for cross-site navigations but still swap when needed for security (e.g., isolated origins).
--product-version	Outputs the product version information and quit. Used as an internal api to detect the installed version of Chrome on Linux.
--profile-directory	Selects directory of profile to associate with the first browser launched.
--profiler-timing	Configure whether chrome://profiler will contain timing information. This option is enabled by default. A value of "0" will disable profiler timing, while all other values will enable it.

--remote-debugging-address	Use the given address instead of the default loopback for accepting remote debugging connections. Should be used together with --remote-debugging-port. Note that the remote debugging protocol does not perform any authentication, so exposing it too widely can be a security risk.
--remote-debugging-port	Enables remote debug over HTTP on the specified port.
--remote-debugging-socket-fd	The given value is the fd of a socket already opened by the parent process. This allows automation to provide a listening socket for clients to connect to before chrome is fully fired up. In particular, a parent process can open the port, exec headles chrome, and connect to the devtools port immediately. Waiting for chrome to be ready is then handled by the first read from the port, which will block until chrome is ready. No polling is needed.
--remote-debugging-socket-name	Enables remote debug over HTTP on the specified socket name.
--remote-debugging-targets	Porvides a list of addresses to discover DevTools remote debugging targets. The format is :,...,:port.
--renderer	Causes the process to run as renderer instead of as browser.

--renderer-process-limit	Overrides the default/calculated limit to the number of renderer processes. Very high values for this setting can lead to high memory/resource usage or instability.
--renderer-startup-dialog	Causes the renderer process to display a dialog on launch. Passing this flag also adds kNoSandbox on Windows non-official builds, since that's needed to show a dialog.
--renderer-wait-for-java-debugger	Block ChildProcessMain thread of the renderer's ChildProcessService until a Java debugger is attached.
--renderpass	No description
--repl	Runs a read-eval-print loop that allows the user to evaluate Javascript expressions.
--report-vp9-as-an-unsupported-mime-type	Force to report VP9 as an unsupported MIME type.
--require-audio-hardware-for-testing	When running tests on a system without the required hardware or libraries, this flag will cause the tests to fail. Otherwise, they silently succeed.
--reset-app-list-install-state	If set, the app list will forget it has been installed on startup. Note this doesn't prevent the app list from running, it just makes Chrome think the app list hasn't been enabled (as in kEnableAppList) yet.
--reset-variation-state	Forces a reset of the one-time-randomized FieldTrials on this client, also known as the Chrome Variations state.
--restore-last-session	Indicates the last session should be restored on startup. This overrides the preferences value. Note that this does not force automatic session restore following a crash, so as to prevent a crash loop. This switch is used to implement support for OS-specific "continue where you left off" functionality on OS X and Windows.
--root-layer-scrolls	Handles frame scrolls via the root RenderLayer instead of the FrameView.
--rtl	No description
--run-all-compositor-stages-before-draw	Effectively disables pipelining of compositor frame production stages by waiting for each stage to finish before completing a frame.

--safebrowsing-disable-extension-blacklist	Disables safebrowsing feature that checks for blacklisted extensions.
--safebrowsing-manual-download-blacklist	List of comma-separated sha256 hashes of executable files which the download-protection service should treat as "dangerous." For a file to show a warning, it also must be considered a dangerous filetype and not be whitelisted otherwise (by signature or URL) and must be on a supported OS. Hashes are in hex. This is used for manual testing when looking for ways to by-pass download protection.
--SafeSites	No description
--sandbox-ipc	Causes the process to run as a sandbox IPC subprocess.
--save-page-as-mhtml	Disable saving pages as HTML-only, disable saving pages as HTML Complete (with a directory of sub-resources). Enable only saving pages as MHTML. See http://crbug.com/120416 for how to remove this switch.
--screen-config	Specifies the initial screen configuration, or state of all displays, for FakeDisplayDelegate, see class for format details.
--screenshot	Save a screenshot of the loaded page.
--scripts-require-action	Notify the user and require consent for extensions running scripts. Appending --scripts-require-action=1 has the same effect as --enable-scripts-require-action (see below).
--search-provider-logo-url	Use a static URL for the logo of the default search engine. Example: https://www.google.com/branding/logo.png
--secondary	No description
--secondary-display-layout	Specifies the layout mode and offsets for the secondary display for testing. The format is "<t

--service-request-channel-token	The token to use to construct the message pipe for a service in a child process.
--service-runner	The value of the
--shared-files	Describes the file descriptors passed to a child process in the following list format: <file_id>:<descriptor_id>,<file_id>:<descriptor_id>,... where <file_id> is an ID string from the manifest of the service being launched and <descriptor_id> is the numeric identifier of the descriptor for the child process can use to retrieve the file descriptor from the global descriptor table.
--shill-stub	Overrides network stub behavior. By default, ethernet, wifi and vpn are enabled, and transitions occur instantaneously. Multiple options can be comma separated (no spaces). Note: all options are in the format 'foo=x'. Values are case sensitive and based on Shill names in service_constants.h. See FakeShillManagerClient::SetInitialNetworkState for implementation. Examples: 'clear=1' - Clears all default configurations 'wifi=on' - A wifi network is initially connected ('1' also works) 'wifi=off' - Wifi networks are all initially disconnected ('0' also works) 'wifi=disabled' - Wifi is initially disabled 'wifi=none' - Wifi is unavailable 'wifi=portal' - Wifi connection will be in Portal state 'cellular=1' - Cellular is initially connected 'cellular=LTE' - Cellular is initially connected, technology is LTE 'interactive=3' - Interactive mode, connect/scan/etc requests take 3 secs

--show-md-login	If true, the views-based md login and lock screens will be shown.
--show-non-md-login	If true, the non-md login and lock screens will be shown.
--show-overdraw-feedback	Visualize overdraw by color-coding elements based on if they have other elements drawn underneath. This is good for showing where the UI might be doing more rendering work than necessary. The colors are hinting at the amount of overdraw on your screen for each pixel, as follows: True color: No overdraw. Blue: Overdrawn once. Green: Overdrawn twice. Pink: Overdrawn three times. Red: Overdrawn four or more times.

--simulate-upgrade	Simulates an update being available.
--single-process	Runs the renderer and plugins in the same process as the browser
--site-per-process	Enforces a one-site-per-process security policy: * Each renderer process, for its whole lifetime, is dedicated to rendering pages for just one site. * Thus, pages from different sites are never in the same process. * A renderer process's access rights are restricted based on its site. * All cross-site navigations force process swaps. * <iframe>s are rendered out-of-process whenever the src= is cross-site. More details here: - http://www.chromium.org/developers/design-documents/site-isolation - http://www.chromium.org/developers/design-documents/process-models - The class comment in site_instance.h, listing the supported process models. IMPORTANT: this isn't to be confused with --process-per-site (which is about process consolidation, not isolation). You probably want this one.
--skip-gpu-data-loading	Skip gpu info collection, blacklist loading, and blacklist auto-update scheduling at browser startup time. Therefore, all GPU features are available, and about:gpu page shows empty content. The switch is intended only for layout tests. TODO(gab): Get rid of this switch entirely.
--skip-nostore-all	No description
--skip-nostore-main	No description
--skip-reencoding-on-skp-capture	Skips reencoding bitmaps as PNGs when the encoded data is unavailable during SKP capture. This allows for obtaining an accurate sample of the types of images on the web, rather than being weighted towards PNGs that we have encoded ourselves.
--slow	Defines that Material Design visual feedback animations should be slow.
--slow-connections-only	No description

--touch-events	Enable support for touch event feature detection.
--touch-noise-filtering	Tells Chrome to do additional touch noise filtering. Should only be used if the driver level filtering is insufficient.
--touch-selection-strategy	Controls how text selection granularity changes when touch text selection handles are dragged. Should be "character" or "direction". If not specified, the platform default is used.
--touch_view	No description
--trace-config-file	Causes TRACE_EVENT flags to be recorded from startup. This flag will be ignored if --trace-startup or --trace-shutdown is provided.
--trace-export-events-to-etw	Enables the exporting of the tracing events to ETW. This is only supported on Windows Vista and later.
--trace-shutdown	Causes TRACE_EVENT flags to be recorded beginning with shutdown. Optionally, can specify the specific trace categories to include (e.g. --trace-shutdown=base,net) otherwise, all events are recorded. --trace-shutdown-file can be used to control where the trace log gets stored to since there is otherwise no way to access the result.
--trace-shutdown-file	If supplied, sets the file which shutdown tracing will be stored into, if omitted the default will be used "chrometrace.log" in the current directory. Has no effect unless --trace-shutdown is also supplied. Example: --trace-shutdown --trace-shutdown-file=/tmp/trace_event.log
--trace-startup	Causes TRACE_EVENT flags to be recorded from startup. Optionally, can specify the specific trace categories to include (e.g. --trace-startup=base,net) otherwise, all events are recorded. Setting this flag results in the first call to BeginTracing() to receive all trace events since startup. In Chrome, you may find --trace-startup-file and --trace-startup-duration to control the auto-saving of the trace (not supported in the base-only TraceLog component).
--trace-startup-duration	Sets the time in seconds until startup tracing ends. If omitted a default of 5 seconds is used. Has no effect without --trace-startup, or if --startup-trace-file=none was supplied.
--trace-startup-file	If supplied, sets the file which startup tracing will be stored into, if omitted the default will be used "chrometrace.log" in the current directory. Has no effect unless --trace-startup is also supplied. Example: --trace-startup --trace-startup-file=/tmp/trace_event.log As a special case, can be set to 'none' - this disables automatically saving the result to a file and the first manually recorded trace will then receive all events since startup.
--trace-to-console	Sends a pretty-printed version of tracing info to the console.
--trace-to-file	Sends trace events from these categories to a file. --trace-to-file on its own sends to default categories.
--trace-to-file-name	Specifies the file name for --trace-to-file. If unspecified, it will go to a default file name.
--trace-upload-url	Sets the target URL for uploading tracing data.
--translate-ranker-model-url	Overrides the URL from which the translate ranker model is downloaded.
--translate-script-url	Overrides the default server used for Google Translate.
--translate-security-origin	Overrides security-origin with which Translate runs in an isolated world.
--true	Value indicating whether flag from command line switch is true.
--trusted-download-sources	Identifies a list of download sources as trusted, but only if proper group policy is set.
--try-chrome-again	Experimental. Shows a dialog asking the user to try chrome. This flag is to be used only by the upgrade process.
--try-supported-channel-layouts	Instead of always using the hardware channel layout, check if a driver supports the source channel layout. Avoids outputting empty channels and permits drivers to enable stereo to multichannel expansion. Kept behind a flag since some drivers lie about supported layouts and hang when used. See http://crbug.com/259165 for more details.
--type	Indicates the type of process to run. This may be "service-manager", "service-runner", or any other arbitrary value supported by the embedder.
--ui-disable-partial-swap	Disable partial swap which is needed for some OpenGL drivers / emulators.

--unlimited-storage	Overrides per-origin quota settings to unlimited storage for any apps/origins. This should be used only for testing purpose.
--unsafe-pac-url	Pass the full https:// URL to PAC (Proxy Auto Config) scripts. As opposed to the default behavior which strips path and query components before passing to the PAC scripts.
--unsafely-allow-protected-media-identifier-for-domain	For automated testing of protected content, this switch allows specific domains (e.g. example.com) to skip asking the user for permission to share the protected media identifier. In this context, domain does not include the port number. User's content settings will not be affected by enabling this switch. Reference: http://crbug.com/718608 Example: --unsafely-allow-protected-media-identifier-for-domain=a.com,b.ca
--unsafely-treat-insecure-origin-as-secure	Treat given (insecure) origins as secure origins. Multiple origins can be supplied. Has no effect unless --user-data-dir is also supplied. Example: --unsafely-treat-insecure-origin-as-secure=http://a.test,http://b.test --user-data-dir=/test/only/profile/dir
--use-angle	Select which ANGLE backend to use.

--use-fake-ui-for-media-stream	Bypass the media stream infobar by selecting the default device for media streams (e.g. WebRTC). Works with --use-fake-device-for-media-stream.
--use-file-for-fake-audio-capture	Play a .wav file as the microphone. Note that for WebRTC calls we'll treat the bits as if they came from the microphone, which means you should disable audio processing (lest your audio file will play back distorted). The input file is converted to suit Chrome's audio buses if necessary, so most sane .wav files should work. You can pass either to play the file looping or %noloop to stop after playing the file to completion.
--use-file-for-fake-video-capture	Use an .y4m file to play as the webcam. See the comments in media/capture/video/file_video_capture_device.h for more details.
--use-first-display-as-internal	Uses the 1st display in --ash-host-window-bounds as internal display. This is for debugging on linux desktop.

--use-system-default-printer	Uses the system default printer as the initially selected destination in print preview, instead of the most recently used destination.
--use-test-config	Initializes X11 in threaded mode, and sets the
--use-viz-hit-test	WindowServer uses the viz hit-test logic (HitTestAggregator and HitTestQuery).
--user-agent	A string used to override the default user agent with a custom one.
--user-always-affiliated	Always treat user as affiliated. TODO(antrim): Remove once test servers correctly produce affiliation ids.
--user-data-dir	Directory where the browser stores the user profile.
--user-gesture-required	Autoplay policy to require a user gesture in order to play.
--user-gesture-required-for-cross-origin	Autoplay policy to require a user gesture in ordor to play for cross origin iframes.
--utility	Causes the process to run as a utility subprocess.
--utility-allowed-dir	When utility process is sandboxed, there is still access to one directory. This flag specifies the directory that can be accessed.
--utility-cmd-prefix	The contents of this flag are prepended to the utility process command line. Useful values might be "valgrind" or "xterm -e gdb --args".
--utility-run-elevated	No description
--utility-sandbox-type	Type of sandbox to apply to the utility process. Options are "none", "network", or "utility" (the default).
--utility-startup-dialog	Causes the utility process to display a dialog on launch.
--v	Gives the default maximal active V-logging level; 0 is the default. Normally positive values are used for V-logging levels.
--v2-sandbox	Enable the V2 sandbox during the helper executable initialization.
--v2-sandbox-enabled	The command line paramter indicating that the v2 sandbox is enabled. This must be different than the "v2-sandbox" flag to avoid endless re-executing. The flag tells the sandbox initialization code inside Chrome that the sandbox should already be enabled. TODO(kerrnel): Remove this once the V2 sandbox migration is complete, as processes will be assumed to run under the V2 sandbox.
--v8-cache-options	Set options to cache V8 data. (off, preparse data, or code)
--v8-cache-strategies-for-cache-storage	Set strategies to cache V8 data in CacheStorage. (off, normal, or aggressive)
--validate-crx	Examines a .crx for validity and prints the result.
--validate-input-event-stream	In debug builds, asserts that the stream of input events is valid.
--variations-override-country	Allows overriding the country used for evaluating variations. This is similar to the "Override Variations Country" entry on chrome://translate-internals, but is exposed as a command-line flag to allow testing First Run scenarios. Additionally, unlike chrome://translate-internals, the value isn't persisted across sessions.
--variations-server-url	Specifies a custom URL for the server which reports variation data to the client. Specifying this switch enables the Variations service on unofficial builds. See variations_service.cc.
--version	No description

--video-threads	Set number of threads to use for video decoding.
--video-underflow-threshold-ms	Allows clients to override the threshold for when the media renderer will declare the underflow state for the video stream when audio is present. TODO(dalecurtis): Remove once experiments for http://crbug.com/470940 finish.
--virtual-time-budget	If set the system waits the specified number of virtual milliseconds before deeming the page to be ready. For determinism virtual time does not advance while there are pending network fetches (i.e no timers will fire). Once all network fetches have completed, timers fire and if the system runs out of virtual time is fastforwarded so the next timer fires immediatley, until the specified virtual time budget is exhausted.
--vmodule	Gives the per-module maximal V-logging levels to override the value given by --v. E.g. "my_module=2,foo*=3" would change the logging level for all code in source files "my_module." and "foo." ("-inl" suffixes are also disregarded for this matching). Any pattern containing a forward or backward slash will be tested against the whole pathname and not just the module. E.g., "/foo/bar/*=2" would change the logging level for all code in source files under a "foo/bar" directory.
--voice-interaction-supported-locales	List of locales supported by voice interaction.
--wait-for-debugger	Will wait for 60 seconds for a debugger to come to attach to the process.

--windows10-custom-titlebar	Enables custom-drawing the titlebar and tabstrip background so that it's not a garish #FFFFFF like it is by default on Windows 10.
--winhttp-proxy-resolver	Uses WinHTTP to fetch and evaluate PAC scripts. Otherwise the default is to use Chromium's network stack to fetch, and V8 to evaluate.
--wm-window-animations-disabled	If present animations are disabled.
--yield-between-content-script-runs	Whether to split content script injections into multiple tasks.
--zygote	Causes the process to run as a renderer zygote.
