It is good, but this Addon is incompatible with a lot of Components like Menu Notifications and Popups…
If this Issues are solved you get 5 Stars.

Sadly this can not be fixed. As the way popups and notifications are implemented, and the way HTML5 fullscreen works. Only if you fullscreen whole page, you will see notifications and popups in fullscreen mode.
