It's about the very best you could ever hope for from a free add blocker. It doesn't always work 100% of the time but it works like 99.99% of the time and it rarely breaks websites

Great add-on and perfectly blocked almost all the ads I received before. Thank you for your great works

Tried to block an ad from Marketplace on Facebook in my Chat and it did not work. It seems a great app otherwise

Very good app

Excellent! Very easy to use. Blocks a lots of garbage. I use it for years now.

The best of the blockers

This Add is perfect to avoid so many unnecessary pop-up windows, I am very satisfied with this job so well done, thanks Addblock!
