File associations, firefox

[Karl Auer]

Hi there.

Having upgraded to Firefox 1.5, I now can't seem to find any way to add
file associations within Firefox. I want to tell it to run javaws when
it sees a ".jnlp" extension.

More generally though, where does one set up file associations in
Ubuntu/GNOME? If I have a file, I can use "Open with" to set up an
association with files of that type. I can also look at the properties
of such a file and use the "open with" tab. That tab only allows me to
select from existing applications or to add a new app, the remove button
is greyed out.

Similarly with Firefox; I get the feeling that as an ordinary user I
don't have sufficient permissions to change file associations. Although
if I start Firefox as root (sudo firefox) it has *fewer* associations,
and I still can't add anything.

So - where are they, so I can get at them with sudo?

Regards, K.
