#1 - If you really understand what all those icons mean on your toolbar, make it smaller. Size does not matter here. Make it smaller by clicking the menu bar and View -> Toolbars -> Customize -> Use Small Icons.
#2 - StumbleUpon, Yahoo! Toolbar. Status Bar, MegaUpload, etc. If you don?t use it often, clear out all the mess from View -> Toolbar. Better still, only leave the navigation bar intact.
#3 - F11 means full screen in Firefox. This is the fastest way to get a bigger Firefox screen.
#4 - FullerScreen is a Firefox plugin than enhances full screen mode by hiding the remaining toolbars and statusbar. All the toolbars will be in auto-hide mode and you can make it appear again by moving your mouse to the edge of the screen.
(#5 - If you are still unsatisfied with the screen size, it is time to start saving some money and buy a bigger monitor!)
2) Use Compact Menu 2 extension. This will collapse the Menu Bar into one button and let you put that button on any tool bar and than shut off the Menu Bar. In my screen shot it's the blue globe with the black down word arrow. https://addons.mozilla.org/en-US/firefox/addon/4550
That's it.
I also use the AutoHide extension. By far the best full screen extension for any browser period. Total control over what tool bars show and autohide. No tool bars at all with this extension but they all autohide simply by moving the cursor to the top of the screen. Been using it for years. http://www.krickelkrackel.de/autohide/

Doesn't hide all the tool bars nor does it autohide the hidden ones. The Autohide extension gives you total control over all tool bars including the Status bar.
