Chose It After Trying 4 Others — The Best In Blocking Bad Habits! Bewertet mit 5 von 5 Sternen

I tried 4 addons to limit access to time stealing websites. None of them worked better than this one. Some were fancier, some had more functions, some didn't work. This one does work and is easy to control. It gives me a blank screen where there used to be a website.
Update: I'm using Comodo Firewall content filter now to block websites..
