Firefox is now the last major browser that still supports uBlock Origin
摘要
文章报道 Firefox 在 Bluesky 上表态不会放弃对 uBlock Origin 的支持，回应了 Microsoft Edge 即将因迁移到 Manifest V3 而停用基于 Manifest V2 的广告拦截扩展的消息。文章解释 Chromium 系浏览器（Chrome、Edge、Opera、Brave 等）在 Google 主导下逐步淘汰 Manifest V2，而 Firefox 是少数非 Chromium 浏览器且唯一仍支持 uBlock Origin 的主流浏览器，Safari 和 DuckDuckGo 不支持。对 uBlock 忠实用户而言，Firefox 是唯一无需妥协的选择，其他浏览器只能使用功能较弱的 uBlock Origin Lite 或内置拦截功能。

原文
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.
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.
This is officially Firefox's killer app. I will never go back to Chrome so long as uBlock Origin is supported on Firefox.

But Firefox is one of the few web browsers remaining that isn’t based on Chromium, and it’s now the only major browser to still support uBlock Origin. Neither Safari nor DuckDuckGo—the two other major non-Chromium browsers out there—support uBlock Origin.
For die-hard uBlock Origin fans, Firefox appears to be the only browser left without compromises. With any other browser, you’ll need to settle for uBlock Origin Lite (with fewer features and less ad-blocking success) or whatever built-in ad-blocking feature comes with the browser.
