Recently drop down menus in Firefox, apart from the bookmarks menu, have become black and the items appear only when the mouse hovers over them: thus only one item can be seen at a time, not the full list. How can I restore the white drop down men with all items visible?

Moving to Firefox Support.

Have you tried starting Firefox in Mozilla Safe Mode? http://kb.mozillazine.org/Safe_mode
If no improvement using Safe Mode, do you have the same problem if you create a new profile and test it with no extensions or non-default themes installed?

When things work properly in Safe Mode but not in Standard Mode it often indicates that an installed extension is causing problems. Try disabling all extensions but one and then close and restart the program. (Disable them by using menu path Tools->Addons->Extensions->click on "Disable" for every extension but one.) See if the problem is present. If not, enable an additional extension and close and restart the application. Repeat this procedure until the problem reappears. The last enabled extension will be the cause of the problem.

Problem seems to have been due to an extension(Add-on Update Checker)

Thanks for identifying the problem extension as others may be seeing the same problem.
