Did you disable all the extensions before restarting?
If it works in Firefox Safe-mode then disable all extensions (Tools > Add-ons > Extensions) and then try to find which is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
In Firefox Safe mode these changes are effective:
*all extensions are disabled
*the default theme is used (no persona)
*userChrome.css and userContent.css are ignored
*the default toolbar layout is used (localstore-safe.rdf)
*the Javascript JIT compiler is disabled
*hardware acceleration is disabled
*plugins are not affected
*preferences are not affected
