Every time I go into Mozilla, it adjusts the screen back to crt mode. I cannot seem to get it to reset. When not in Mozilla, the widescreen is okay.

Check that you do not run Firefox in compatibility mode or with a reduced screen resolution. You can open the Properties of the Firefox desktop shortcut via the right-click context menu and check the "Compatibility" tab. Make sure that all items are deselected in the "Compatibility" tab of the Properties window.
