ecurbh said the copy/pasting of your pic properties should work near the same in mozilla as in IE... Not sure why it wasn't working.
Ask him if it works if I open york up in yahoo and paste and go to mozilla for FR. That's what I was doing because York didn't show me registered under mozilla. Maybe I was just missing a charcter or something but I got it working. Opening FR from yahoo might not have had a thing to do with it.
