My menu bar is missing and it doesn't come back temporarily when I press either Alt or Alt + F10 together.
My menu bar has disappeared. The directions on the support site say the first steps to restoring are to start Firefox in safe mode & then to press the Alt button so that the bar can come up temporarily. I started Firefox in safe mode two different ways, but nothing happened when I pressed the Alt key except that the screen moved down a little bit & moved back up when I pressed it again. I got the same result when I pressed Alt & the F10 key together, which was also suggested. I would appreciate it if you would advise as to what I should do to restore the menu bar. Thanks.

You only need to press F10 and not Alt + F10.
This can be a problem with the file localstore.rdf in the Profile Folder.
Delete localstore.rdf or rename the file to localstore.rdf.sav in the Profile Folder to test if the file is corrupted.
See http://kb.mozillazine.org/Corrupt_localstore.rdf
(caution: do not delete the localstore.rdf file in the Firefox program installation folder)
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
- Don't make any changes on the Safe mode start window.
See:
- Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems
- Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
- Use "Disable all add-ons" on the Safe mode start window to disable all extensions.
- Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
