AppleScript and JavaScript for Automation to get frontmost tab’s url and title of various browsers.
-- AppleScript --
-- This example is meant as a simple starting point to show how to get the information in the simplest available way.
-- Keep in mind that when asking for a `return` after another, only the first one will be output.
-- This method is as good as its JXA counterpart.
-- Google Chrome
tell application "Google Chrome" to return title of active tab of front window
tell application "Google Chrome" to return URL of active tab of front window
-- Google Chrome Canary
tell application "Google Chrome Canary" to return title of active tab of front window
tell application "Google Chrome Canary" to return URL of active tab of front window
-- Chromium
tell application "Chromium" to return title of active tab of front window
tell application "Chromium" to return URL of active tab of front window
-- Safari
tell application "Safari" to return name of front document
tell application "Safari" to return URL of front document
-- Webkit
tell application "Webkit" to return name of front document
tell application "Webkit" to return URL of front document
-- This example will return both the title and URL for the frontmost tab of the active browser, separated by a newline.
-- Keep in mind that to be able to use a variable in `tell application` — via `using terms from` — we’re basically requiring that referenced browser to be available on the system.
-- That means that to use this on "Google Chrome Canary" or "Chromium", "Google Chrome" needs to be installed. Same for other browsers.
-- This method also does not exit with a non-zero exit status when the frontmost application is not a supported browser.
-- For the aforementioned reasons, this method is inferior to its JXA counterpart.
tell application "System Events" to set frontApp to name of first process whose frontmost is true
if (frontApp = "Safari") or (frontApp = "Webkit") then
using terms from application "Safari"
tell application frontApp to set currentTabTitle to name of front document
tell application frontApp to set currentTabUrl to URL of front document
end using terms from
else if (frontApp = "Google Chrome") or (frontApp = "Google Chrome Canary") or (frontApp = "Chromium") then
using terms from application "Google Chrome"
tell application frontApp to set currentTabTitle to title of active tab of front window
tell application frontApp to set currentTabUrl to URL of active tab of front window
end using terms from
else
return "You need a supported browser as your frontmost app"
end if
return currentTabUrl & "\n" & currentTabTitle

// Safari
Application('Safari').documents[0].name()
Application('Safari').documents[0].url()
// Webkit
Application('Webkit').documents[0].name()
Application('Webkit').documents[0].url()
// This example will return both the title and URL for the frontmost tab of the active browser, separated by a newline.
// This method is superior to its AppleScript counterpart. It does not need a "main" browser available on the system to reuse the command on similar ones and throws a proper error code on failure.

Camino

Used to be present (see revisions) but the browser itself was discontinued.

Opera

Used to be present (see revisions) but AppleScript support was removed. Even when it had AppleScript support, it was undocumented.

Firefox

Absent since although it’s possible to get the window’s title, it’s not possible to get its URL (it used to be, in versions prior to and including 3.5). It’s possible via hacky ways that consist of sending keystrokes, but those can be unreliable. This bug is being tracked in Bugzilla.
