Why on earth would the Mozilla people set the mail client to behave this
way?
Mozilla applications handle those things based on their own stuff/code
(mime types, network protocols... are all in charge of Firefox/
Thunderbird).
On linux systems that causes a bit of mess because every desktop
environment (GNOME, KDE...) has its own defined rules for taking care of
this and they collide. So usually, users has to make some tweaks to get
the behaviour they want.
