I uninstalled the program, restarted and installed Firefox 4.Now the Help/About screen says Firefox 4,but the appearance is Firefox 3 with no orange box in the upper left. It also says "Google Monzilla Firefox" in the uppermost . Can you help me put Firefox 4 back on my computer. I have uninstalled Chrome, but have G-mail if that helps. '

You see the orange (on Linux gray) Firefox button if the Menu Bar is hidden (View > Toolbars > Customize or right-click a toolbar).
You can hide or make the Menu bar visible via View > Toolbars, also accessible via Firefox > Options.
If you need to access the hidden Menu bar then press F10 or tap the Alt key to make the Menu Bar appear temporarily.
