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.

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

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

Version 1.63.0 will randomly cause partial freezing of the browser after running for a while, and it can only be resolved by restarting the extension process in about:process.

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

It blocks A LOT of stuff, it works well for a lot of websites, but it also blocks useful stuff: sci-hub, some government website pop-up windows, etc.
