Hello, your addon marked as corrupted. Please fix it. Best adblocker

This has been working great for years, but the recent update broke everything. It's blocking a lot of CSS & JavaScript files now, so sites don't look or function correctly, so am haing to disable for now. Hoping this gets fixed soon and I can revert to 5 stars.

since yesterday block EVERYTHING ! that update u made ... worst so far - no idea if sites add some blocking for the app or not but u kinda overdo it ... a lil :D

Since a couple weeks nearly every page is not working with adblock. Im annoyed a bit.

Очень слабая блокировка, все равно вылезает огромная куча всего ненужного, что я перестал видеть после перехода на другой блокировщик. Главная проблема - начала глючить сама Мозилла, половина сайтов не загружалась, или загружалась с серьезными ошибками. Я грешил на браузер и потратил уйму времени, чтобы его починить, но все прошло, как только отключил Adblocker Ultimate. Ищите лучшее решение. Оно есть.

This no longer work. Now Youtube and facebook just fail to load. God forbid you dont view their precious ads

no longer working.

This worked great, but the last update has made basically every website (besides a very small selection) fail to load. Not sure what you've done, but hopefully it gets fixed or I'll have to uninstall.

this worked fine for a long time but in the last 48 hours it's stopped working some site like facebook wont load at all when this is turned on youtube and things like hotmail also is not working when then is enabled
this was a 5 star addon but now its unusable

Has been working well for a long time but is recently stopping websites working entirely (facebook, youtube etc)

as of 8-4-25 your ad blocker does not work on YouTube I had to remove all my play lists b/c of ads

Loved it, until it stopped working for YT on 6/10/25

when it works it works, but lately it rarely works. especially on youtube

YouTube has been down since this morning

YouTube videos only play for the first minute for some reason.

War schon einmal besser.

This use to work great at blocking ads on YouTube, but not now. It makes it so it says I have no internet, until I shut it off. When I turn it back on, it lets at least one ad thru. It also is blocking necessary links from working on sites like SSA, TurboTax, etc. I'm disappointed.

Hello.
The extension not works on YouTube, it says there is no internet, when I turn off the extension, YouTube works.

No longer blocks ads (no the sites are not whitelisted on my end).
