Have you tried starting Firefox in Mozilla Safe Mode? http://kb.mozillazine.org/Safe_mode
If no improvement using Safe Mode, do you have the same problem if you create a new profile and test it with no extensions or non-default themes installed?

In what way did you try to fix it?
...also, try clearing your cache....or, this...

From a prior post from Dan Raisch (with minor changes) ...

(If using a version below Firefox 3.5.) Clear the browser cache (Tools->Clear Recent History->select cache->click on "Clear Now" button).

Else... use menu path Tools->Options->Advanced->Network tab->click on "Clear Now" button.)

Delete any cookies relating to the site(s) involved (Tools->Options->Privacy->Show Cookies button).

Note: The above is for Windows so if you're using a different OS refer to this...
