Comment 9 for bug 423856

For the FF exception part, approved. It seems rather important to me to not keep outdated instances around with potentially unapplied security updates, and this is just a simple local notification which should help admins to keep their system current.

I agree that this is just the counterpart of the apt-get update cronjob. It ought not to send any system specific data, of course, just ask the server about the most recent version. But I let you discuss/decide that.
