Rated 5 out of 5 stars

This is simple and easy. Auto-hides and also has a hot key to hide/show. You can set the amount of milliseconds to show/hide too. The only thing is that after I installed it and restarted FF, all my tabs were hidden so I couldn't see the tab that opens to the Hide Tab website, and i didn't know how to show/hide the tabs. Easily resolved by displaying all add-ons in FF, and then opened the options for Hide Tab. Works exactly as i wanted and hasn't yet interfered with my other add-ons (All in One Sidebar and Bookmark Autohider) which I thought were likely to be affected.

This review is for a previous version of the add-on (0.7.3).
