In Firefox 3.6 on Windows you can hide the menu bar via "View > Toolbars" or via the right click context menu on a toolbar. Press and hold the Alt key down to bring up the menu bar. Go to "View > Toolbars" or right-click the menu bar or press Alt+V T to select which toolbars to show or hide.

To get your menu bar back press ALT V T M in that exact order and your toolbar should be back!

Please mark this as solved if this worked

I tried pressing ALT V T M in order. The view window came up as if I had clicked on it, but it did not solve the back, forth and bookmarks from being missing.

Try ALT V T N

That should work

Thanks for the reply. They do appear, but in shadow form and unusable. Same with the Bookmarks. Still not working. Any help out there is appreciated. :)

Jean,

Try reverting to the Default theme (Tools > Add-ons > Themes).
