- google's manifest v3 has no analouge to the
webRequestBlocking
API, which is neccesary for (effective) adblockers to work - starting in chrome version 127, the transition to mv3 will start cutting off the use of mv2 extensions alltogether
- this will inevitably piss of enterprises when their extensions don't work, so the
ExtensionManifestV2Availability
key was added and will presumably stay forever after enterprises complain enough
You can use this as a regular user, which will let you keep your mv2 extensions even after they're supposed to stop working
In a terminal, run:
sudo mkdir -p /etc/opt/chrome/policies/managed /etc/opt/chromium/policies/managed
echo '{ "ExtensionManifestV2Availability": 2 }' | sudo tee /etc/opt/chrome/policies/managed/policy.json /etc/opt/chromium/policies/managed/policy.json
- enable developer mode
- upon rebooting, go into vt2 (shift+ctrl+right arrow function key)
- log in as root
- type in
/usr/libexec/debugd/helpers/dev_features_rootfs_verification && reboot
- upon rebooting, go into vt2 again and log in as root
- run the commands from the linux section
Open regedit, and create Software\Policies\Google\Chrome\ExtensionManifestV2Availability
in HKEY_LOCAL_MACHINE as a dword set to 0x00000002
In a terminal, run:
defaults write com.google.Chrome ExtensionManifestV2Availability 2
(note that i haven't tested this for mac. please let me know if it doesn't work)
Windows 11 here, there is no google in my HKEY_LOCAL_MACHINE Software\Policies\
Edit: I managed to make the keys/folders uptil Software\Policies\Google\Chrome\ and then tried to make the dword ExtensionManifestV2Availability but the dword does not seem to be able to accept 0x00000002
Edit 2: I removed the 0x and only put in 00000002 and it seems to have worked.
So basically if you dont have those folders make them yourself they are called keys in the new menu and then when you get to \chrome make a dword called ExtensionManifestV2Availability and set it to 00000002.
Please let me know if anything I did here is wrong. Thanks a lot for the guide!
