better than uBlock Origin

Everything is fine, but ads in the kinopoisk.ru (one of the most popular RuNet sites) is not blocked. Never. It is very annoying.

非常优秀的免费广告拦截扩展，用了很久了，支持拦截国内优爱腾视频网站片头广告，不会出现黑屏倒计时，很好用。但是Mozilla可能受到国内广告商的压力，屏蔽了包括这个扩展在内的广告拦截扩展页面，以后火狐的使用门槛更高了，对使用火狐的国内用户更不友好了。

This addon breaks a lot of sites and requires too much manual configuration for the average/novice user. Good if you like to configure based on preferences and you are able to, otherwise not so great.
