This is a must have! Rated 5 out of 5 stars
It's amazing! It even protected me on a graphics site that had got a serious pop-up problem. It's a must have and my anti-spyware programme has had no major spyware since firefox and no minor at all since this add-on! I could go on and on singing it's praises! I'm not well up on what to block so the choice of an easy list was another plus point.This review is for a previous version of the add-on (0.7.5).
