Great, it's was I looking for. Show the addonbar on fullscreen when hoving at bottom. But it´s have a bug. When in fullscreen, minimizing and then restoring, the address and tab won't appear. Fix it please!!!!!This review is for a previous version of the add-on (6.3.0).
This should be fixed in 6.3.1, which is available at: https://addons.mozilla.org/en-US/firefox/addon/fullscreen-toolbar-hover/versions/6.3.1
