Hint for Linux users Rated 5 out of 5 stars

For those who couldn't install this great addon on Linux, I say you *can* install it ;-)Click on "Add to Firefox" - it'll say that the addon is not compatible with your system, but click on "Install for Windows anyway" (I think this is it)... et voilà :-)
Just to mention... I'm using it on Firefox 17.0.1 and Linux Mint 13, and it's working great ;-)

This review is for a previous version of the add-on (2.7.2).
