I removed Firefox from Applications and restarted: same behavior. I removed Firefox from Applications and renamed Firefox in Library/Application Support to "Firefox old" and restarted: same behavior. See the attached screen shot of this last attempt. I guess I'm using Safari (like I am now to enter this).
