Hide Menus in Fullscreen with Autohide for Firefox

I was reading about Autohide yesterday over at lifehacker and had the plan to try it today to see if it was a useful add-on for mozilla firefox. Autohide manipulates the interface of firefox when entering fullscreen mode (F11) - you can select to (auto) hide certain bars and menu entries to have more space for the website itself. The following settings can be changed:

You may choose to always show the status bar or only on activity, you may hide all toolbars that are currently installed including the google and stumbleupon toolbar if they are installed on your system. The same can be done for the tab bar and the windows taskbar. Now, whenever you move your mouse over an hidden item (such as the menu bar) it becomes visible and you can interact with it normally.

The direct opposite of hidding certain items can also be configured which would be show always. If you can’t live without the tab bar and status bar you can select to have them always on. They never hide when you press F11 and go into fullscreen mode.

This application can benefit users with older displays and users who like to have all the information present on the screen.
