I go and open Firefox, and there is only a blank tab on the screen. There is no tool bar, navigation bar, right-clicking gives no needed options and by pressing "alt " there is no temp option screen that appears.

'''Menu Bar''' (File, Edit, View, History, Bookmarks, Tools, Help) Press ALT+ V T M (CTRL+V T M on Macs) on your keyboard. This should restore the menu bar (Firefox 3.6) '''Other toolbars''' View|Toolbars|Select the desired Toolbar '''Other steps to try''' Try restoring the default set by going to View|Toolbars|Customize| Restore Default Set. This will put the toolbars back in the default place '''Safe Mode''' You May need to reset toolbars and controls via [[Safe Mode]] Make sure you completely close Firefox first. When you get to the Safe Mode window, select Reset toolbars and controls and then Make Changes and Restart. Hope this helps!
