Thank you Mr. Hill and all the guys on github that donate their free time to update the filters all the time, in this never ending cat-and-mouse play between you guys and websites.
For all of you that gave uBO a negative review, please read the documentation. If it works fine for millions of people, the problem is obviously on your side. You are either installing uBO on top of another adblocker which only causes them both no to work, or you have a free AV that sells your data and compromises your machine or you have a corrupted OS.

Топчик

Самый лучший и эффективный блокировщик. Блокировать можно просто ненужный и лишний контент, из-за которого интернет стал очень тяжёлым и монструозным.

since years mx favorit adblocker! keep your great work and thanks!

Extremely easy to insstall, even for me

Far and away the best blocker I've ever used. It's extremely lightweight, it makes pages load faster, it's simple to use and configure, and it's effective at what it does without breaking websites. On top of all that, it's completely free and open-source.

There really aren't any downsides I can think of compared to other, similar extensions. This is always the first extension I add on a clean installation of Firefox, and I recommend it to everyone who needs an adblocker or element blocker.
