You're quite right. Thanks for the reminder, I confess I DID forget about that. That being said, I think it was Firefox introducing them that caused the shift in the way people used a browser. I remember people asking me to set up Firefox because IE didn't have tabs. Nobody ever asked me to set Opera up for me. But yes, absolutely credit where credit is due.
