I have this on laptop and I haven't any issues I just put Firefox on phone so lets see

this addon become very heavy (slow start), and after latest firefox esr 52.9 update no internet and 100% cpu usage, so i switched to adblocker ultimate

Recently I can see more and more websites with ads which uBlock fails to block. There are websites that detect uBlock easily and block their content unless I switch it off. Another drawback is that it is sometimes impossible to pick elements for blocking on certain websites with no error message displayed (I consider this a bug). I think it's time to look for other ads blocking software...

Не блокирует на Youtube. Тормозит.

nice app

Blocks content which is actually necessary. No cool!

Why Youtube sometime got blank if ublock turn on?
can you help me?

It's not able to work on multiple CPU?
about:config. When I wrote "dom.ipc.processCount" and other commands to multiple.

Bellissima

Не срабатывает на старте браузера. Вылезает вся возможная реклама на странице, которая установлена стартовой. Приходится несколько раз обновлять страницу, прежде чем сработает.

Doesn't block Google analytics

很棒

This extension has worked great for me for a long time. HOWEVER, as of around April 17, 18, 19 or so, a new code from Facebook has caused this extension to prevent all the links in Facebook from working. I hope that in an update (?) of uBlock it will work all right again. I tried disabling a lot of other extensions I use. In this case it was uBlock that was causing the problem. It's a great extension, and I'm betting it will be fixed soon.

Très heureuse tant que ça fonctionnait (j'aurais mis 5 étoiles), mais je découvre ce matin que uBlock n'apparaît plus sur mon navigateur, je constate que les deux versions ne sont pas (plus ?) compatibles. Malheureusement je ne peux pas acheter un nouvel ordinateur pour bénéficier de la dernière version de FF... :-(
Galère !

on Youtube, it still play video ads on the actual video so when you full screen, the title changes to the "ad" title breaking the video and still has some leftover adspace, which can be solved using the block element.
While comparing to Chrome's ublock origin, these problems isn't present. Still a great ad-blocker
