The first error you mention, permission denied in nsIAutoCompletePopup::selectedIndex, is a problem internal to the browser. It happens when you call for that first debugging alert(), and it seems to have something to do with calling alert() within an event handler on a text field. These things come and go in Firefox. In short, it's not your fault, it doesn't seem to have any real effect, and you need not worry about it.

The second error you mention, element has no properties, is happening because document.getElementById() finds elements by their |id| property, not by their |name| property. Your HTML sample contains no element with an id of "f1".
