Rated 5 out of 5 stars

Excellent add-on and I like how it's under constant development and reacts to what's happening on the web in regards to unwelcome scripts and techniques.
You do have to enable some sites manually and have some minimal awareness of scripts and unwanted sites obviously so it's not for everybody, but it's your choice to install it so 5 stars from me.

This review is for a previous version of the add-on (1.6.9.3).
