Does firefox upgrades need some pre/post install love to close and restart firefox during upgrades

[Adam Pribyl]

One new idea here: how about to use installonly=2 option for firefox like 
we do for a kernel?

Would it work to have two installations o FF, but /usr/bin/firefox 
script will point only to a new one? In this case, it would make a sense 
to display message "Firefox was updated. Restart?", but the old 
installation will work.
