Excellent Rated 5 out of 5 stars
When I became aware of all the privacy and security issues related to cross site requests, I was hoping Firefox had a built-in option to block these requests by default. While I was sad to learn that this was not the case, this excellent addon has fulfilled that critical role. I think it should come default with the functionality of the browser. Great, simple interface and well-thought out temporary permissions model.This review is for a previous version of the add-on (0.5.3).
