easy, simple and doesn't eat my memory.
'Nuff said!

lets me block exactly what I want and nothing else.

Good

It does the thing that I installed it to do: block sites. User interface is plain and simple, which I like.

basic and beautiful interface

works fine!

I liked this addon
But i don't want even a second to be displayed
The website address also appear

great blocker, blocks all url's even just specific sections of websites.

Nice
But some websites that are blocked still can appear
Please fix it

Awesome!

Otimo

fantastic,I WANTED TO BLOCK YOUTUBE AND IT HAS DONE

Enfin un site efficace pour bloquer les sites indésirables. Paramétrable et surtout doté d'un mot de passe pour protéger ses proches et soi-même. TOP !

A lifesaver app. Works like clockwork. Has enough features for most personal customization. Using in FF 57.0

awesome

It works just fine.

Works exactly as advertised. If there's a site that you don't want to see, add it to the list. Your browser will show a notice that the site is blocked and you get a blank page. Very handy for blocking sites that are simply time-wasters or otherwise offensive.

Works Perferct

Efficient and easy. Very good add-on!
