Rated 3 out of 5 stars
I downloaded this because I have some virus that was automatically redirecting to other sites and my anti virus software couldn't detect it. It worked great for the sites I added but unfortunately it also blocks many other sites not on my list. Even getting to this site I had to change my leechblock setting to get to this page. A big hassle but for now until I can find software to find the virus I will have to put up with it.This review is for a previous version of the add-on (0.4.3).
