BEST!

I can't imagine myself browsing the internet without uBlock... EVER!
An effective blocker and convenient hands-off experience!

The first thing to install after firefox (or any browser really..) is this. uBlock is such an important and incredible tool! It is extremely easy to use but has quite a lot of customizability, if needed.
Thank you for your hard work!

Yes, about the gocomics review below: I had the same issue, but just went to the dashboard, then filters list, then manually updated them (clock icon). Voila, problem solved. I love this add-on. What's particularly nice is the element picker and element zapper. Thanks so much!!!

Blocks 95% annoying pop up ads. Very happy
