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.
You mean open York in IE? Yahoo is a site, not a browser.
You should theoretically be able to do that. if you select the properties and "copy" in IE and switch to Mozilla you should still have it on the clipboard to paste.
