This extension is fantastic. Why I haven't found this earlier?

It became my habit to open Facebook. Most of the time I don't even now when I have opened the tab. Now with this extension, I open Facebook only when I actually need this.

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

Does not work with certain websites on Android (youtube, webtoons)

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!
