slows down firefox & makes it unresponsive for several seconds at a time Rated 1 out of 5 stars

Yikes, even changing the options of other add-ons took a long time so long as this one was installed. Also what I was really hoping for was the ability to blacklist the "from" site from sending the referrer. For example I don't want google to send the referrer (especially the search terms!) when I follow a result link (I can't find a way to do this other than to use https google).

This review is for a previous version of the add-on (0.8.16).
