How do I change the resolution to view Firefox in the same size as the other applications on my laptop?


The screen while using Firefox appears to be in a 800 X 600 mode while the remainder of the programs are in a 1024 X 768 mode.

Check that you do not run Firefox in compatibility mode or with a reduced screen resolution.

You can check that in the "Compatibility" tab in the Properties via the right-click context menu of the Firefox desktop shortcut.
Make sure that all items are deselected in the "Compatibility" tab of the Properties window.
