works great on most websites, youtube often has some issues though, most commonly with ads displayed on the homepage. furthermore you need a github account to report errors, which i think isnt very good.

It blocked my Bookmarks Toolbar! (Had to remove!)

Addendum: Tried again & lost my bookmarks again. Had to remove again.

Conflitto con gboard. Accettando un suggerimento di gboard, il testo viene aggiunto anziché sovrascritto. Problema risolto disattivando questo plugin.

Google has made it so you can't watch youtube videos if you have this program active on your computer. By active I mean running at all even if it is disabled for youtube. If you go to settings and turn it off there so that it is not active for any websites then you can use youtube pretty reliably otherwise you will have buffering problems and slow videos.

здравствуйте расширение перестало блокировать рекламу в домашней странице яндекса

Successfully blocks ads but has critical side effects: most sites with graphs/pics doesn't work properly: google maps, desmos, binance etc, just black screen instead of map, graphs, charts...

Efficace. Mais trop gourmand. Rend mon firefox très lent.

Not working on Russian garbage sites

Works ok but does not work as well or as comprehensively as Ublock did on chrome. Frustrating because I went from seeing NO ads to having to block the same ads again and again once a page is refreshed.

Supposedly ublock works best on firefox, so if anyone knows how to help it take full effect, please comment on this. Because I am so frustrated trying to get rid of ads on firefox with this!!

Guess YouTube/Google introduced a new anti-uBlock feature - cause it breaks YouTube. If enabled - random videos go blank showing this message: "Video unavailable
This content isn't available, try again later." Disabling uBlock works just fine. :\

Doesn't work with twitch anymore.

As of October 1, 2025, YouTube is blocking videos unless "uBlock Origin" is disabled while using Firefox v143.0.3.

Youtube is blocking ublock AGAIN.

The extension often doesn't open when you want to disable restrictions for some sites.

Great for blocking ads, but broke YouTube playlists. Have to manually go to next video when this extension is active.

Good extension but youtube ads arent blocked anymore...

Alas PayPal wil not work with this, otherwise its good.

Тормозит загрузку видео в Youtube

dopo mesi di utilizzo perfetto, oggi yutube mi blocca dicendo di togliere ublock per continuare il video. spero aggiorniate perche era veraemnte utile
