Full screen Firefox

Problem: This is a tough one. You want to display firefox in full screen like when pressing F11 in windows. That means, removing:
-the menu bar
-the address bar
-the tabs
-the bookmark toolbar and any other toolbar

The problem is, the option doesnt exist in firefox.

Solution 1: There is a free full-screen browser called Plainview. However, as the name suggests, it is very restricted in features. This is not an alternative to Firefox.

Solution 2:
It took me a while but I managed to have an almost-full-screen firefox as shown on this shot of my whole screen:



Thanks to different elements combined, which are:
-A Firefox extension called Full Screen
-A Firefox extension called full fullscreen, that removes the address bar and toolbars when applying the first add-on
-A hack that sets the behaviour of the menu bar to hide when Firefox is the active window. The bar just reappears when the cursor is held on the top of the screen.

For this hack:
-Open the application folder where firefox.app is.
-Right-click on firefox.app
-Select "show package contents"
-Open the the "contents" folder
-Edit the file info.plist with TextEdit for example
-Just below <dict> on line 6, insert the following two lines:

<key>LSUIPresentationMode</key>
<integer>4</integer>

Now, just right click on a page and click "toggle full screen". That's it :-)
