It is really good, haven't had any problems so far. From time to time, Youtube manages to bypass it and show me ads, but in some hours (days, worst case), the problem is fixed. Highly recommend it!!

Its AdBlocker very well!

It simply works - the best you can say about any Internet app today

There are still sites in Brazil that manage to bypass AD, but overall it's very good!

Even though substack.com is whitelisted, it interferes with how some pages work. They won't load properly. Also, it forgets, and I have to re-disable it on the site. Substack.com should be whitelisted by default since it doesn't run ads.

I hope it will get updated to work with the new firefox update!
