Linux compability? Rated 4 out of 5 stars

I do have "Hide Caption Titlebar Plus 2.6.0" installed - but can't update to the newest version. Why?

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

Great addon Rated 5 out of 5 stars

Great especially for people who want to get rid of the titlebar in linux like it's possible in windows (tabs ton top).
One thing that I still can't get right: True Fullscreen whilst watching html5 youtube videos. There's still the "Firefox" and "minimise, maximize, close" button.
