Just by installing the extension and setting a specific blacklist rule in a new browser window, I could block a stupid-ass scammer website that denied me all access to my browser, without needing to close all tabs in my first browser window. Very nice!

Facil de usar y ofectiva

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

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!

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 !
