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
Clearing the Cache and removing Cookies is only a temporary solution. Restart the computer and the problem persists.
Incidentally this is not a problem for Internet Explorer - just Firefox.
