Rated 5 out of 5 stars

Does what it says it does, works fine for me under Firefox 7.0.1 and just what I was looking for.

Anyway no idea about the ad's that others are mentioning here but if there are any, there all blocked with ABP and a HOSTS file (extra layer for blocking ad's amongst other things).

This review is for a previous version of the add-on (2.0.1.1-signed).
