  "account": "Firefox has announced that it will continue to support uBlock Origin, despite Microsoft Edge planning to block the popular ad-blocking extension. The transition comes as Microsoft Edge migrates from Manifest V2 to Manifest V3, a new browser engine architecture. This move will restrict ad-blocking extensions from accessing essential functions needed to effectively identify and block ads during web browsing and video playback. While Microsoft Edge, based on the Chromium open-source browser engine, is following Google's lead, Firefox remains unique among major browsers. Safari and DuckDuckGo, two other non-Chromium browsers, do not support uBlock Origin. For fervent uBlock Origin users, Firefox currently stands as the sole major browser without any compromises. Users of other browsers will be limited to uBlock Origin Lite, which offers fewer features and ad-blocking effectiveness, or built-in ad-blocking features provided by their respective browsers.",
