Just noticed that. Open Add/Remove programs, find FM FireFox Entry and click "Click here for support information" link.
If you see what I see you probably will be all like "Whoa!.."
If not, then probably it's just me, but what I see is that the "Comments:" string is not wrapped so the pop-up window goes way beyound my screen width (1200x800).
[EDIT] Actually not WAY beyound, just a little, but anyway.
