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

When you purchase through links in our articles, we may earn a small commission. 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.
