by the time you're reading this, this probably no longer works since the policy has been removed. I reccomend you to check out https://github.com/r58Playz/uBlock-mv3 instead
- google's manifest v3 has no analouge to the
webRequestBlockingAPI, 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
ExtensionManifestV2Availabilitykey 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
