Sorry for the dups.  The server timed out the first few times I submitted it,
and I didn't get any emails about the others.

The association for calling from Firefox needs to be made within Firefox.  
I don't know whether FF knows to look into the Windows registry to find MIME 
type, or extension-based, associations (and I have no idea how these 
associations might be made under the Mac, Linux or other OS's); however, that is 
the only way that this association could be handled automatically.

It's true that TB doesn't know how to open an http: or https: URL on its own, 
even if the MIME type is message/rfc822.  I'm not sure that it should.  Instead, 
when the FF user clicks on the file, FF will check what the default action 
should be; if "Open" then the file is downloaded to a temp directory and passed 
off to the app.  In Windows at least, once this happens, the MIME type 
information is lost -- TB therefore needs to know how to handle a generic file 
(which might not even have the .EML extension).  This requires bug 242959 to be 
fixed, at a minimum.

Looks like a duplicate of Bug 261559.

I'm pretty sure FF is looking at the system mime database in win2k since it is
trying to call OE here.

This bug is asking for an association (Bug 261559), so I'll dup it to that.  But
that won't help until bug 242959 is fixed...
