Finally, an efficient blocker. Easy on CPU and memory.
IMPORTANT: uBlock Origin is completely unrelated to the site "ublock.org".
uBlock Origin is not an "ad blocker", it's a wide-spectrum content blocker with CPU and memory efficiency as a primary feature.

- (2024-12-20) Grégory Fleury: Is Mostly unable to block ads from GAFA, especially facebook and youtube (black screen of death). I suspect they let those filter like did adblock several years ago.
- (2024-12-06) Saint Esprit & Co: Just today in France, Youtube found a way to block Ublock by not allowing video for more than one 59 seconds, after that, loading endlessly... Hoping for a quick solution with an update ^^
- (2024-12-02) Laurence Gough: Best Chrome extension around. When this stops working, hello Firefox!
- (2024-11-26) _: 追記 2024/10/15現在、uBlock Originがいずれ使えなくなることが確定したので、uBlock Origin liteかEdge アドオンのuBlock Originに移行推奨します。 gliastudioの目障りでうっとおしい動画広告が要素ブロックでも遮断できない ↑ページのソース表示からgliastudio広告と思われるソースを虱潰しに特定してマイフィルターにぶち込んだら、消すことが出来ました。(その場合、音声の消し忘れにご注意を)
- (2024-10-20) uBlock Origin is simply the best. A must have for human kind.
- (2024-10-16) Filip: Does its job. I obstructed over 1.5 million advertisements by now since installation. I read the news moments ago, and it saddens me to see one of my favorite extensions go into the dustbin of history. Google sucks!
- (2024-10-16) Pedro A. López-Valencia: Usen uBlock Origin Lite o migren a Firefox, donde ¡uBlock Origin funciona perfecto! Es una lástima que ManifestV3 la ha hecho inútil en todos los navegadores basados en Chromium.
- (2024-10-14) Seasight: IF GOOGLE KILLS UBLOCK, I'M SWITCHING TO FIREFOX
- (2024-10-03) Seungguk Ahn (KOR_APUcard): 이게 광고 뿐만 아니라 내가 차단을 원하는 요소도 선택해서 차단해버릴 수 있어서 좋았는데, 이제 지원 중단이라니... 이제 누가 이 기능 대신 해주냐...
- (2024-09-30) SetupEditor: On some sites, when we delete an element on a page It may be that element is needed on another page and we are not aware If the plugin has the ability to display the previously deleted element when it is in element selection mode We can solve the problem of displaying the contents of the text ContentBlockHelper plugin that uses this feature let's use
- (2024-09-20) Shadonic: Hasn't been blocking ads on multiple sites lately, but it completely stopped working for Twitch altogether. I have the custom filters added and everything, but ads always play regardless of what I change. This extension had a good run, but it's kind of garbage now.
- (2024-09-14) Eric Ketzer: Edit Sept 6th 2024. It works perfectly. Absolutely the best one. (Original evaluation) So far so good. It blocks some annoying ads I had for months on streaming sites and on yahoo that Adblock Plus failed to block.
- (2024-09-02) 5 stars for the developers who worked on this. Do to Google forcing Manifest V3 Framework, those new compatibility requirements will eventually force us to switch to uBlock Origin Lite. Thank you for continuing to make a compatible version of this extension. I'm happy it exist for those moments when forced to use Chrome. When I can avoid using Chrome, I will do so. For everyone else who has a choice, consider switching to browsers that treat you better. Such as Brave Browser with its own native AdBlock and Privacy features, and keep Chromium compatibility (Desktop & Mobile). Firefox is also notable, since as of now retained Manifest V2 framework. Meaning you can use the original uBlock Origin extension.
- (2024-08-19) Arjen San Miguel: EDIT (8/19/24): still works for me, but in the event it stops... google chrome can suck my cawk n ballz. i'm moving browsers if this happens.
- (2024-08-14) Hamza Zaman: Google,a data company, whihc steals it's suer data, truly sucks, and this extension helps them stop that greedy habit. Kudos to the creators. Love uBlock Origin.
- (2024-08-09) Joann: Still the best ad blocker. Literally blocks all kinds of ads on every website. Edit (2024/08/09): UBLOCK ORIGIN IS STILL THE 🐐 AD BLOCKER AND GOOGLE KNOWS THEY CAN'T BEAT THEM THAT'S WHY THEY DECIDED TO GET RID OF THEM INSTEAD
- (2024-08-08) Amazing Ameya: I'm here till Death! Full Support to uBlock Origin
- (2024-08-07) Edit 8/7/2024: It was known for about a year Chrome was going to effectively kill this essential, must-have extension, so I knew I had to leave Chrome behind. I've moved to Firefox a few months ago, was able to bring all my bookmarks and most of my extensions with me, including uBlock Origin. Even found a few extensions that are not available in Chrome. Changing your workflow can be hard, but it actually turned out to be pretty easy. Zero regrets! So long Chrome and thanks for all the fish.
- (2024-08-04) I've been very happy with this utility for a very long time, but I'm mostly now just disappointed that Google is apparently full-bore evil now. There are other browsers, and other video services and utilities, something I think they've forgotten somewhere along their way to whatever greedy corporate hellhole they now live in.
- (2024-08-01) If Google ends support for uBlock Origin, it's goodbye Chrome and hello Firefox.
- (2024-08-01) Kenan Yusuf Temel: It's been so good until lately but it needs to be updated. Youtube opens so slow it can't get rid of the ads that fast.
- (2024-07-27) J J: Google is killing off UBO. Will dump Chrome for Firefox.
- (2024-07-25) ixshads: really good besides the need for adblock as i can personally block things now too! good work on constantly releasing fixes for the youtube ad problem too, this crew is amazing ! edit jul 25 24: still super good but unfortunately isnt optimizing well anymore, causing various sites to sigtrap. unfortunate but still works on most sites fine.
- (2024-06-18) Tim Colbeck: You fix YouTube, I'll donate $20. AND I'll change my rating. FIX IT.
- (2024-06-16) 下条朝人: 自分は対象になってないからわからないけど、YouTubeのサーバーサイド広告に対応したみたいです。昔の情報のままになってて外部フィルター入れてしまう人多いけど、今はデフォルトのフィルターが一番いいです。豆腐フィルタや餅フィルタはYouTubeで誤動作起こしたことがある。なんJAdGuard部にすごくよくまとめられてるので読む価値ありです。自分は広告ブロックに興味持ってGithubとか見るようになったけど、新しい広告とか不具合とかはデフォルトのフィルターが断然対応早い。足すなら補足フィルターのAdGuard Japanese filter Plus。あとAdGuard JapaneseはEasyListの補足フィルターだからEasyListをオフにしちゃいけない。
- (2024-06-08) TheWolfSharp: Update june 8th 2024: Google now limits your internet speed if you're using this addon... It's becoming increasingly more and more common for ads to pop-up despite the use of this adblocker, I'm getting increasingly concerned that it might stop working sometime soon. I really don't wanna get beer commercials while trying to see a scene of a movie I like.
- (2024-06-07) Dwight Schrute: Very good plugin - blocks harmful popup ads (that are still common on certain mainstream media sites still in 2021....) However only reason why I give it 4 and not 5 is because its now blocking me from opening any mail in gmail. This is really annoying so I have to disable it. Update 2024-06-07 no longer works on blocking ads.
- (2024-06-06) Abyss Guardian: No ad-blocker is better than uBlock Origin! Ever since I started using this extension, I've never looked back to other ad-blockers. Kudos for the developers to combat YouTube's ad-block detection! Could never stand YouTube's ads.
- (2024-06-02) David Esteban: when tienes una extension que borra los anuncios :V xDXDXDXDXXDXD
- (2024-05-26) AND: Слетают настройки. Точнее настройка остается, но перестает работать. Пока ту же строку в фильтре не продублируешь/удалишь-не важно. Главное, что-то поменять и снова заработает. Но это как-то не радует каждый раз ручками лазить( UPD Навязчивый банер говнояндекса никак не заблокировать
- (2024-05-22) 異常に重くなりページ表示されなくなったけども再インストールで元に戻る。やはりこの広告ブロッカーは優秀。
- (2024-05-06) uBlock Origin is an absolute must-have Chrome extension for anyone looking to enhance their browsing experience. This powerful ad blocker efficiently filters out intrusive ads and trackers, significantly speeding up page load times and offering a cleaner, more streamlined web browsing experience. Beyond just blocking ads, uBlock Origin gives users fine-grained control over what content to block, making it customizable to suit individual preferences. It’s lightweight, easy to use, and remarkably effective. If you're concerned about privacy and want a clutter-free Internet, uBlock Origin is the perfect tool for you.
- (2024-04-22) Bart Simpson: Нормально работает, спасибо. -- Добавлено спустя два года: -Ребята-разработчики, вы лучшие! Этот ваш продукт- он шедеврален, серьезно, чесслово!)) Очень доволен. Все бы так делали. -- Шел 2024 год... Все отлично! Спасибо!!!

- (2024-03-29) tianxin: literally amazing, helps to block youtube ads too (edited 2024 29 march)
- (2024-03-26) Rodrigo Sambade Saá: Una extensión imprescindible, sobre todo desde que Adblock Plus empezó a admitir anuncios aceptables.
- (2024-03-25) the best ever
- (2024-03-22) Nika Nakaidze: Cant block web page elements in gmail
- (2024-03-22) Mary Sangria: Полностью игнорирует рекламу Яндекса. Тупо не работает на любом Яндекс сервисе.
- (2024-03-12) renaissance18: we need a update again
- (2024-03-06) Todo Lo mejor: Se encontro alguna solucion para youtube?
- (2024-02-26) Bohdan: Started to work very poorly
- (2024-02-23) José Henrique: A TARDE A EXTENSÃO NÃO ESTÁ FUNCIONANDO CORRETAMENTE, O MESMO ESTÁ DEIXANDO PASSAR TODA A POLUIÇÃO QUE EXISTE NOS SHORTLINKS E O MESMO ESTÁ SENDO IDENTIFICADO EM SITES
- (2024-02-23) 大畑乃之: バックアップ・ファイルの上限を設定出来る様にして、旧いバックアップ・ファイルが自動削除されると助かる。後、バックアップは一回で全ての項目がバックアップされる様には成らんのか。其れか上書き保存。きちんとしてないとファイルが嵩張るし。 2022年4月7日追記: 前日迄閲覧出来て居たサイトが閲覧出来なく成るって事は有るらしいしなあ…然も四月三日の更新。 翌日から可笑しく成った。 何処を変えたんだろう。 2022年7月7日追記: 表示されなく成る箇所が亦殖えてる。フィルタの問題?! 2022年11月23日追記: Easy Privacyも一時解除か永久解除かが選択出来る様にして欲しい。 2023年9月25日追記: 少しでも不具合が起こると前に設定したフィルタが消えてるんだが… 2023年9月29日追記: サイト毎に処理済み事項と未処理事項の識別が出来ると良い。 2023年11月7日追記: strict1p/3pとは?! よく解らない。構文に関する良い説明書がヒットしないし。 2024年2月23日: youtubeに関して。検索結果の段階で何故か勝手に動画のページに飛ぶ様に成ってる―このアドオンをオフにしているシークレット・モードに於いてだが―。
