See:

Remove the files in the updates and updates\0 folder.
You may need to delete active-update.xml and updates.xml as well if present.

C:\Users\<user>\AppData\Local\Mozilla\Firefox\Mozilla Firefox\updates
(%LOCALAPPDATA%\Mozilla\Firefox\Mozilla Firefox)

The "Application Data" folder in XP/Win2K and the "AppData" folder in Vista/Windows 7 are hidden folders.

For whatever reason, deleting those files temporarily resolves the issue. Something, I haven't yet determined what causes is, makes this glitch reappear over and over. It might be as a result of updates, but I am not certain.
