I do not think their solution helps. I am already way thru their extension 
code (see 
and what it is doing is, that it every 5s checks wherether there is a file 
/var/lib/update-notifier/user.d/firefox-3.5-restart-required with newer 
timestamp compared to last time this extension was woken up. If yes then 
notify restart. But as firefox files are already modified and missig on a 
filesystem, this restart would be equal to what we see now on Fedora. FF 
needs to be killed before update, and started afterwards.

The other solution would be to install to the same directory. As FF 
updates are not that huge, the running instance would have its files 
modified, but would not crash most probably, then making a notification to 
restart make sens.
