I _think_ that Cybe was asking what application type? The program is
Firefox, you are trying the change the 'Application' as in
Edit|Preferences|Applications in Firefox.

Those 'Applications' typically are set on first run and picked up from
your mime settings. They should also change if you've changed the
default opening program in Nautilus. For example 'MPEG Video' may have
'Use Movie Player (default)' as the default. In Nautilus I can change
that to use VLC as the default & FF _should_ pick up the change.

However, sometimes the mime file gets corrupted. You can change modify
directly in ~/.mozilla/firefox/<default profile>/mimeTypes.rdf - just
open that in gedit and edit. You can also simply rename/mv the file and
let FF rebuild a new one on restart.
