Outstanding Add-on. Highly customizable, and not a single glitch. If you take about 15 minutes to play with the settings, you'll find something you like. Be sure to check out the developers page to see additional info for certain features like making it so the addon can't be disabled. I don't get the comments from people who say it didn't work or they couldn't find the options...I assume they weren't trying...at all...

The aplication is working without any strange bugs. I'm personaly using it with the ''Block site'' as a second security option and the browser have no problems with it. Easy recommendation.

Davvero ben fatta! Quasi come un vero firewall!! Mi piace e la consiglio!. Su yoube tube è presente anche il videoguida, con i 12 passi per utilizzare al meglio il filtro web

Works perfectly. Can't use the blocked site anymore, just as I wanted.

Simple and works. Two things missing - shortcut to block page, and option to skip confirmation pop-up forever.

This app is percect, clear, simple, straight to the point, possibility to put a random password so as not to be tempted.
Is it planned to port it to Android?
Thanks!
