Initialize mozilla prefs on startup every time. That is necessary if

	* embed/mozilla/mozilla-notifiers.h:

	Initialize mozilla prefs on startup every time. That is necessary
	if people change them with gconf-editor. This is a 10 ms regression
	on startup but ... it's necessary. What worries me more is the 130 ms
	the notifiers registration takes, that's odd.
