mailto in registry changed when Firefox updates
Even though another application is selected under Options-Applications for "mailto", it still changes the mailto to FireFox in the registry under HKEY_CLASSES_ROOT\mailto\shell\open\command and HKEY_CLASSES_ROOT\mailto\DefaultIcon.
This only happens when FireFox updates itself. It does not happen when FireFox starts.
