- Some users report not blocking certain sites or non-functionality.

Best find for Android. A blocker that works on mobile Firefox. It's super lightweight and, most importantly, completely non-intrusive – no annoying ads or popups.
The 5-rule limit on the free version is very fair because you can just swap rules whenever you need. I just treated myself to the pro version since there's a sale right now.
My wish for the future: a built-in Pomodorro timer and the ability to create separate lists for different tasks.
Thanks for a clean tool!

The free version only has 3 rules... but it works better than Foxfilter.

High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
