Rated 5 out of 5 stars

This is an excellent extension; useful for netbooks and other small screens. It would be great if the shortcut has an option to permanently show the menu bar/status bar.

This review is for a previous version of the add-on (0.3.2). 

..

you can permanently show the bars with the key by disabling the autohiding stuff in the preferences. just set the first of the values to 0
