Excellect Ad blocking extention for firefox

По кд сбрасываются настройки, делается специально, включая допустимую рекламу.

很开心它能屏蔽CSDN的各种脑残div

Fantastisch programma.

The only reason I don't give it five stars is you have to use the blocking option over and over instead of it being permanent. Otherwise this does a good job.
