How do I fix the toolbars issue I'm having whenever I open Firefox 4?

more options

EVERY time I open Firefox 4, the entire window flashes black, and the only way to stop it is to right click on a toolbar (between a flash) to bring up the menu and check or uncheck to view one of the toolbars.

On my PC, I had the same problem but I thought I fixed it when I reset my toolbars. I've reset my toolbars a few times on my notebook, with no success. The issue occurs even in Safemode, with all addons disabled and settings reset.

I'm at a loss. What can I do to fix this?

Try a new profile (Profile Manager - Create, remove or switch Firefox profiles) or a clean reinstall (Reinstall firefox), does it work?

A new profile does not fix the issue. And before I reinstall Firefox I just thought of something. When I do the temporary fix of checking or unchecking a toolbar the new Firefox button disappears, no matter which toolbar I select. Could the button be the reason for the flashing?

A reinstall (following the directions linked) does not solve the issue. I'll do a full backup tomorrow and do a clean reinstall... Because hey, you never know.

Even after doing a clean reinstall, I can't seem to get it to not be borked every time I open Firefox. Very frustrating.

The "magic" of windows strikes again. I restarted my computer and now Firefox opens properly. I still don't have the new Firefox button, but not anything I'm going to cry over.
