It's an excellent ad blocker. works great, the filters are really good and it works wonders.

Amazing, works like a charm !

いつもありがとう。firefox上で問題なく使えてます。

Absolutely amazing! I was using Brave for a while, but I ended up coming back to Firefox with uBlock Origin. It’s just such a great combination!

The best ad blocker. Still works great for Youtube ads.

This extension is a must have when watching YouTube. I have never seen a single ad since I started using it in March 2026. It blocks all YouTube ads and allows you to immediately start watching videos, unlike another adblocker I tried called Adguard, which would make the screen freeze whenever there's an ad, then you need to reload and wait for a few seconds to watch the video. By contrast, uBlock Origin is a much smoother experience.

By the way, uBlock Origin blocks almost all ads and redirects from every website I visited. Besides, I can customise the filter list to block specific components of a website that i don't want to see.

Thank you for being a hero, keep manifest v2 and uBO alive on fox!
