This app is garbage! Doesn't block ads in Facebook worth a crap! Then, when you tell the people who are supposed to be the support team for it, their answer is "Then don't use it." Pretty good answer for someone trying to promote a product. And, they also ban you from the page where you're supposed to report issues concerning it.

Does not work on youtube

YouTube playback is delayed.

When i have this enabled it wont load my searches

marche pas.

It blocks YouTube, videos cannot be played. I had to delete it.

No longer working on Youtube as of February 2026. Every video fails to load and displays:

"This content isn't available, try again later"

Will update my review if this is fixed in the future.

Does NOT work. Youtube shows "this content isn't available, try again later". Disabling uBlock allows me to watch videos. This only happens when I am logged in. If I am not logged in, then I can leave uBlock enabled.

whitelisting a domain from the popup (by clicking on the gray square) doesn't work, it still blocks that domain.
developer, please fix whitelisting domains from the popup.

Yes it blocks ads but YouTube knows you are using it and forces a delay as long or longer than the ad it blocks

Cela fait depuis des mois qu'il ne marche pas bien du tout avec Youbube et impossible de se connecter par eux sur github, erreur pour se connecter, donc impossible de soumettre leurs erreur pas corrigé depuis longtemps!

Ublock na dzień 30.10.2025 nie zawsze działa po włączeniu YouTube wyświetliła mi się reklama banerowa która zniknęła po odświeżeniu, na filmach na YT mających więcej niż 24 godziny i włączoną monetyzację przez długość trwania reklamy jest czarna plansza i komunikat ,, Dlaczego film nie odtwarza się płynnie - Zobacz dlaczego ''. Potrzebne są zmiany które wyeliminują te błędy. Bo naprawdę dzięki temu rozszerzeniu oszczędza się masę czasu które straciło by się na oglądanie reklam.

Doesn't work on youtube anymore...

Suddenly today again ads on Twitch!

As of Sep 6 this add-on prevents any site from loading in my browser.

Extension does not stop autoplay of videos on espn.com. It does not allow me turn off autoplay. It blocks parts of page that I don't want it to block. Uninstalling. And I have Block Audio and Video selected in the Firefox Autoplay setting but no help there either. Frustrating.

It's completely broken. After 30 seconds no data from any website can be loaded and my CPU goes into into overdrive. The second I disable Ublock the temp drops rapidly and everything starts loading again. Tested multiple times. Was great while it lasted but it is unusable in it's current state.
