I migrated to LeechBlock from another similar add-on. By the versatility and offered customization, I regret to have not moved to this add-on earlier. Absolutely brilliant!

Exactly, what I was looking for. Simple, neat and reliable. Best tool for digital self awareness I know so far

This is an immensely helpful tool for managing distractions. It can be customized in a ton of ways while still being simple to use.

An excellent replacement for StayFocusd (which is available only for Chromium). I would have rated it 5 stars, but I gave just 4 because it's missing one feature I want: remove the count-down timer from the add-on icon, and display it only on the page.

Perfect blocking extension, good UI and customization, lightweight but functional.

I highly recommend it

Serves the purpose what it is meant for . Few instructions are quite long otherwise good product to enjoy the service

Probably the best extension for Firefox

.

This is the best website blocker for firefox!

I am a huge fan of this app and would recommend it to anyone
