Ads take up too much time when watching online videos and I find them very annoying when I'm trying to write emails with the ads flashing on right side of screen. Makes me lose concentration on what I want to write. Thank God for those who invented it!

The first and best Ad-blocker out there. xD

Нормальный блокировщик
