Why not /usr/lib/firefox-2.0/* (this will create an conflict when
updating to official FF2 (update to FC7) ) as i think firefox-2 will
probably don't obsolete firefox2 and so, remember user to uninstall it.

Or simply don't package /etc/gre.d as it is require by other Gecko
applications and provide by official firefox.

What about the users setting? It might get a bit problematic if both use
~/.mozilla/firefox ...
A solution is to substitute the command line (in the desktop file) to
launch the profile manager.
I've done this in the past (with deerpark)
