AdGuard is the best adblock extension for Firefox!

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

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

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.

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

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

Thanks for the reply. I would also like o request that the adon is automatically updated and installed when using Firefox Sync (i guess Firefox needs to review it first) and the ability to add custom URL lists.

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

it works well. Am using 2 browsers...Chrome & Firefox and i have both adguard installed because it works totally well. Highly RECOMMENDED

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