Excellent! Rated 5 out of 5 stars

Essential. If you are tired of seeing weird/annoying/disgusting pictures (bald girl with adult hands on her head? Elderly woman peeling her face off?!? Is this what advertising has come to?) that accompany laughable ads for get-skinny-quick pills, "learn a language in a week" and baldness cures which infest online news websites and phone directories, you NEED this.

This review is for a previous version of the add-on (2.2.1).
