Suddenly I have a South African Facebook occupying my fire fox log in. It won't let me go into my account. When I use Safari on the same Macbook I can get access, so somehow it was become fixed to my fire fox browser. How can I get rid of this South African Facebook block or should I just remove firefox as my long time browser. I've done all the cookie deletes and regular stuff. I'd appreciate some professional help. Regards, Jim
