If you are using a userChrome.css then your CSS code might be broken and you need an update.
Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

DISCLAIMER: modifications made through a userChrome.css file can stop working as Firefox evolves in new releases, and can "break" the interface in serious ways.
