If you start Mozilla with multiple profiles and select "Manage profiles" and you press the Exit button in the "Profiles and Migration" dialog you exit the whole thing. If you on the other side presses the "x" in the topright corner of the "Profiles and Migration" dialog you closes the window and go back to the "Select user Profile". Very weird behavior! Using build 20000105
