uBlock Origin (uBO) is not just an ad blocker, it's an efficient wide-spectrum content blocker.
uBO performs as well as or better than other popular blockers.
uBO is a web browser add-on/extension for content filtering - primarily aimed at neutralizing privacy invasion in an efficient, user-friendly method.
Mozilla Firefox is now the last major browser that still supports uBlock Origin.
For die-hard uBO 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).
Information for users of the Chromium based browsers (Chrome, Edge, Vivaldi, Brave, Opera, Samsung, etc.): No later than August 31, 2026, uBO will be removed from the Chrome Web Store and replaced by "uBlock Origin Lite" and uBO will no longer work.
Do not use uBO with any other content blocker. uBO performs as well as or better than other popular blockers. Other blockers can prevent uBO's privacy or anti-blocker-defusing features from working correctly.
System requirements: Windows 10, 11
You can use uBlock Origin also on these Firefox forks
