Muito eficiente.

Good Add on

Working fine, thanks

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.
