Works as advertised!

Does exactly what you want an ad blocker to do. It blocks ads. Must get for my laptop as well because ads drive me nuts.

Works very well; haven't been annoyed by ads since I got it.

Best Ad Blocker out there!

SUPER

Simple and non intrusive.

I was inundated by ads till I found AdBlocker Ultimate. What a difference! No more ads taking up half my screen and popping up when I am working. I am a loyal user from now on!

Adblocker Ultimate has worked as advertised, integrated well and has not interfered w/ normal operations of Browser. Great JOB!

Полезная штука

Nice addon, thank you

I am using a browser, which allows me to block ads. I don't have time to browse through ads in order to find the text that I want to read.
Thank you, Mozilla!!!

brilliant, as good as the old AdBlock Plus

Can block many ads include youtube ads
