i posted an earlier thread regarding internet explorer to msn, and the vote came back as firefox- downloaded it and love it. but my question is, i have the firefox icon in my dock, but every time i click on it to open firefox, a white slot drive looking thing appears on the screen under my macintosh hd icon, why is this appearing? and how do i get rid of it- when i take it to the trash can, an eject picture comes up, and i cant drag into the macintosh icon???
