Firefox is now the last major browser that still supports uBlock Origin

Firefox recently announced via Bluesky post: “Our support for uBlock Origin isn’t going anywhere.” The moment comes in response to news that Microsoft Edge is soon going to lock out uBlock Origin and other ad-blocking extensions that run on Manifest V2 architecture.

Microsoft’s move isn’t surprising, as Edge is based on Chromium, the open-source browser engine that powers most web browsers today, including Opera, Brave, Vivaldi, and Samsung Browser. Google initiated the migration from Manifest V2 to V3 in Chrome/Chromium, and Microsoft Edge is now following Google’s lead.
