I played around with the textbox autocomplete a bit. I can use objects 
as array-elements (containing the displayValue and the id):

ProviderAutoCompleteResult.prototype.getValueAt = function(index) {
     return this.results[index]['id'];
};

ProviderAutoCompleteResult.prototype.getLabelAt = function(index) {
     return this.results[index]['displayValue'];
};

This way the labels (displayValue) are displayed as autocomplete 
suggestions, but when the user selects an entry the value (id) gets 
filled into the textbox.

Not exactly what I want. Any ideas how to access/store the id of the 
selected entry for later retrieval (while displaying the displayValue)? 
Is there a way to access the textbox from within the 
'ProviderAutoCompleteResult' (nsIAutoCompleteResult) to attach something 
like a 'selectedId' attribute to it?

Thanks for your help!
