A must have addon for this browser. I do not use the internet without it.

fantastic adblocker, whole reason i'm here over chrome

Ublock origin is the number one plugin u should install immedetly when you download firefox or any other browser, especieally in todays age the ads on website gone out of controll making the expirience of looking trough sites worse

It's a essential addon for web browsing in 2025.

Raymond - thank you so much!
Big Techs - shame on you!

I give uBlock Origin 100 out of 5 stars. Thanks for always being there for us.

When I try to play YouTube it keeps spinning

finally a Great working addon

Génial pour éviter la pourriture publicitaire !

I have tried many different ad blockers, and this one is by far the best one available. It comes out of the box with a wide variety of block lists/subscriptions, but it also lets users fine tune everything to their own needs on every site. I use it on all my browsers on all devices, and I can't recommend it more highly. The interface is intuitive yet powerful (especially in Advanced Users mode) and gives insight to which requests are being blocked or allowed. I have been using it since 2015. If you haven't already, download it today!

広告は出なくなりますが、日本語環境では明らかな誤作動がいくつかあります。例えば、
・youtubeの自動翻訳字幕が表示されなくなる。
・日本の安全なサイトを誤ってフィルターでブロックしてしまう事が何回かあった。（例えば日本のペイパルへの接続をこのアドオンはブロックしました）
フォーラムも英語での色々な注意書きが多く、英語以外を母国語とする人はバグ報告も難しい。

While this add-on eliminates ads, it has some obvious glitches in Japanese environments. For example,

- YouTube's automatically translated (English to Japanese) subtitles no longer appear.

- This add-on has mistakenly blocked secure Japanese sites on several occasions. (For example, it blocked connections to PayPal in Japan.)

The forum is filled with various warnings in English, making it difficult for non-native speakers to report bugs.


追記：自動翻訳字幕が表示されるようになりました。ありがとう！
Update: Automatically translated subtitles are now available. Thank you!

Works great!
