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

Firefox says it will keep supporting uBlock Origin even as Microsoft Edge and other Chromium browsers phase it out under Manifest V3.

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.

Once Microsoft Edge moves to Manifest V3, ad-blocking extensions won’t have access to the functions needed to properly identify and block ads that occur while browsing websites and watching videos.
