alt Hacker News"browsers using the ExtensionManifestV2Availability policy will be exempt from any browser changes until June 2025"
To extend ManifestV2 in Chrome, add the text below to a text file, saving and running it as a .reg will create and add a value of 2 to "ExtensionManifestV2Availability" in the HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome key
(When you open/run a .reg file, it updates your registry, usually preceeded by a warning.)
Alternatively, you could do this manually by pressing the Windows key, type "run" (without the quotes) and enter, type "regedit" (without the quotes) and enter, then navigate as far as you can to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome key
You may find there is no "Chrome" key and will need to create it, as well as creating ExtensionManifestV2Availability
--------------------------------------
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome]
"ExtensionManifestV2Availability"=dword:00000002Replies
And IIRC including the quotes in a filename in a save dialog, líke "manifestv2.reg" (incl quotes), will save it with the extension you typed, so you won't end up with 'manifestv2.reg.txt'. So you skip a potentially otherwise needed rename step.
Single command line (Run as Administrator-- you can do that from the Windows key-R dialog by holding CTRL-SHIFT and pressing ENTER):
REG ADD HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome /v ExtensionManifestV2Availability /t REG_DWORD /d 2[dead]
Note that this will also disable Chrome’s DNS Over HTTPS as Chrome disables the DoH resolver by default when the browser is managed by enterprise policies like this one. See the platform-specific links mentioned on the uBlock Origin subreddit [1], many of which also include instructions for enabling the DoH resolver while managing the browser using policies.
