Rated 5 out of 5 stars

Great and essential add-on. I used it since 9 months and it work fine. Very easy to configure for protecting my privacy. I don't understand Mozzila don't include this tool in the Firefox. Moreover, the developer take care of users. If you have a serous problem, go to his forum and ask the question. For me, it is important that developers be responsive, because with each new version of Firefox, a lot do not upgrade their extensions and I have to stop using it.

This review is for a previous version of the add-on (1.47.4).
