Removing Mozilla Mail as the default Mail in Mozilla 1.1

[Peter Walker]

I'm trying to remove Mozilla Mail as my default mail in Mozilla (running
under OS X 10.2).  I've successfully created a User.js file, so that when I
click on a Mail link within a web page, it creates a new message in my
default mail programme (ie. Apple Mail).

For those who have

However, if I try to send a web page (File, Send Page), it still goes to
Mozilla Mail.

Any ideas ?
