You need to uninstall and reinstall the Firefox
This did not solve the problem, the same thing occurs.
Start Firefox in Safe Mode {web link} While you are in safe mode; Press the <Alt> or <F10> key to bring up the tool bar.. Then Tools > Options > Advanced > General. Look for and turn off Use Hardware Acceleration.
Poke around safe web sites and see if there is still a problem. Then restart.
