The FF4 button does not appear in the upper left on my browser
There is supposed to be a FF button in the upper left corner of my browser so that I can change from seeing to not seeing the menu. It is not thre.

To get it you need to hide the menu bar. To do that in the View menu select Toolbars, then click on the "Menu Bar" entry.
If you need access to the menus you can press either Alt or F10 to temporarily display them.
It would have solved it had I not found the FF button already, it is in the lower right hand corner. Thanks though TonyE.
