When logged in as a regular user, and when using system-config-network, going to
Help > Contents opens an instance of Firefox (or the preferred web browser, I
guess) running as root. If one next closes system-config-network, the Firefox
instance survives.

I would think there is no need for the Firefox process to be running as root in
order to read documentation. Leaving it behind the system-* app can moreover
expose the user to great peril if she inadvertently uses that firefox instance.

Marking this High priority, as we probably do not want users to be surfing the
web with root priviledges...

BTW, I have not checked other system-* apps...
