Full-screen mode in Firefox on Mac OS X?

Solution 1:

if you go into the info.plist file for your FireFox application and add in an item for Application UI Presentation Mode you can automatically hide the dock and the menu bar whenever the application is active:

That way as soon as you launch it the menu and dock will disappear and you can just hit the zoom button to fill the entire screen. Tabbing over to the other applications will bring back the dock and menubar as will mousing up to the top and bottom edges when firefox is in focus.

Maybe this help. http://jeff.globl.org/projects/firefox/fullerscreen-1.0x.xpi works for me in OSX 10.5.7 and Firefox 3.5.5
