Great way to save screen space in Linux Rated 5 out of 5 stars

This addon says Windows only. Not sure why, as it insrtalls and runs great in Linux. This remove the fairly pointless space wasting titlebar, saving a nice chunk of vertical space, putting it on par with Chrome in terms of vertical real estate. Highly recommended for all Linux users. Not sure why this functionality isn't included in vanila Firefox, to be honest.

This review is for a previous version of the add-on (2.7.3.1-signed).
