AdGuard is the best adblock extension for Firefox!

Users! Just UPDATE your firefox PLEASE! It works fine!

It's like i like, fast Firefox with no ads.

The beta version works very well, even on facebook on Firefox Quantum. Thanks! Version 2.7.3 stopped working on some websites such as facebook since Firefox 56.

Will this add-on work with my Firefox Nightly57+ andriod phone? Because this add-on I can get it to work on my 64 bit windows 10 creators update laptop using... Firefox Nightly 57 64 bit but...not andriod verison of Firefox nightly. Thank you

Great. Better than ABP for firefox. Even better than ABP totally.

nice but I can't use AdGuard in Android Firefox with 'Avira Browser Safety' extention

it just works! but I need to block ads in Firefox and on iPad, too

works perfect but only with 2 browsers:yandex and sumsung, wish you'll add firefox and etc

AdGuard browser extensions are a great way to protect your favorite browser from ads!
