Black background in Menu and Bookmarks Toolbar
The background colour for the Menu and Bookmarks Toolbar is black and this happens no matter what theme or persona I am using. All the other toolbars will change with the theme but not the two above
This happened
Every time Firefox opened
== upgraded FF 3.6

Did you try to disable (uninstall) the Personas extension? Are you using the Persona and the theme at the same time?
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes). See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. You can use "Disable all add-ons" on the Safe mode start window. You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")
If you have many extensions then you can first enable half of the extensions to test which half has the problem. Continue to divide the bad half that still has the issue until you find which one is causing it.

Try upgrading your graphics driver. I had the same problem and this is the only thing that worked.
