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.

Works great!

Une petite merveille.
Je l'utilise en mode avancé.
J'interdis tout par défaut, pas de script, pas d'images. Et j'autorise le minimum pour que le site soit lisible et plus s'il doit être aussi fonctionnel.
On enregistre nos choix et on peut les sauvegarder, puis les restaurer sur un autre PC.
Il remplace plein d'autres addons, qui deviennent inutiles avec lui.
Merci les développeurs :)
PS je l'utilise sur Firefox, le seul navigateur fiable.

This plugin is very helpfull and works efficient.

Здравствуйте, уважаемый Raymond Hill. Ublock origin хорошее расширение. Но месяцев три-четыре тому назад обнаружил, расширение не блокирует рекламу на главной странице Яндекса. На данный момент реклама на главной странице заблокирована. Не знаю как будет в будущем, просто хочу довести до вашего сведение о существовании такой проблемы. Вероятно Яндекс использовал систему обхода блокировок рекламы.

¡El mejor bloqueador de anuncios que existe! Y lo mejor es que bloquea los anuncios en los videos de youtube, netflix, amazon prime video y mercado play, si pagas un servicio de streaming con anuncios como netflix, no verás anuncios gracias a este poderoso bloqueador.

This extension is the only reason I moved to Firefox. I used it for years on Google based browsers, but this month it stopped working there. Here I am.

Excellent!
It works very well.
It blocks trackers and ads very well.

The best blocking add-on here. Love it

Extension does not stop autoplay of videos on espn.com. And I have Block Audio and Video selected in the Firefox Autoplay setting.
