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

на не которых сайтах не работает

Стал пропускать Яндекс.Директ. :(

used to be very good but now it needs improvement, it keeps refreshing facebook newsfeed non stop in firefox 58.0.2 (64bit)

Please increase the add-on size to 7-8 mb -_- 2mb is so small, isn't it?

I liked this as an add blocker, but it actually blocks every link in every email when using Firefox! Gives a malware warning, with an option of unblocking the link, but this is very worrying. It seems that the adblocker could understand links with the safe03 or whatever it is are not blocked.

Фильтры обновляются весьма медленно, часто игнорирует рекламу и наоборот блокирует полезные окна...

My past rating would have been 4 or 5 stars, but it has dropped because of obnoxious ads getting through, especially from IMDB. That's not acceptable, so I've discontinued using uBlock. Other blockers don't have that problem.
