Rated 5 out of 5 stars

A very good add-on that puts an end to requests going on behind my back. It needs a certain period tough in which one has to manually add trusted sites to the whitelist when browsing them for the first time. But once this is done, it works smoothly in the background and adds very good extra protection. I recommend this in combination with NoScript, Adblock Plus, BetterPrivacy and CookieSafe.

I also experienced a speed boost in browsing, because unnecessary requests are simply blocked, thus websites are displayed earlier.

This review is for a previous version of the add-on (0.5.14).
