Is this only with Firefox or the computer.
Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
Start your Computer in safe mode. Then start Firefox. Try Safe websites. Is the problem still there?
