Simple and very useful!! I recomend this add-on!

awesome, simple and complete feature

good

Free, open-source, with massive abilities to counter many different ways in which you can try to bypass it.
10/10, it only lacks some kind of automatic synchronization with a cloud service like google drive/nextcloud, but still an amazing first-install extension

Simple, effective, and easy. Genuinely everything I could want in a site-blocking extension.

This may, without exaggeration, be the best addon ever uploded to Firefox Addons.

Simple, easy to use and does its job well.

Fantastic!

I really appreciate the simple UI.

It just work:D
Even if I didn't find this addon earlier because of the unintuitive name.
