Strikes where others fail. Automatically advertisement that comes along with a Video that starts by opening a website? No more with this dude. uBlock saved me from getting annoyed several times since I have it today. Thank you!

I read the reviews and badly needed a blocker as i had fake pages popping up on other websites asking to install software etc, and only way of closing them was Ctrl+Alt+Del. And then when restarting Firefox, pages spam page would re-open itself. But since installing uBlock no spam or ads. Fantastic.
