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

doesn't work on youtube starting from 5/6 and i got ads on the sites i read on

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

TheGatewayPundit.Com blocks uBlock Origin. They make their site useless if you block their billions of ads. Please fix this.

Not sure if the extension is causing the problem but on youtube it constantly reloads the page if i do anything like click fullscreen.

Ни в почте майл ру, ни в почте яндекса не может блокировать рекламу

Works very well with Chrome. But my version of Firefox states, quote, "installation aborted as add-on appears to be corrupt". Hmm.
