I've got thus far in my research:-
var contractid = "@mozilla.org/autocomplete
Session;1?type=my_datasource";
var session = Components.classes[contractid].getService(components.
interfaces.nsIAutoCompleteSession);
But where and what would my_datasource be? Please excuse me no
knowing all about this, I am still trying to learn it.
I have looked at both nsIAutoCompleteSession.idl and
nsIAutoCompleteResults.idl on the Mozilla LXR, but I don't know how to
go forward from there ...

I really appreciate you taking the time to set this out but, I'm
sorry, you've lost me.

(heavy breathing) sounds like bad news but maybe not too bad ...
If you have the inclination I would be grateful if you could pick me
up where I got lost and get me going again or point me to somewhere
that has a fairly easy explanation.
