Give this a whirl.. Also, to anybody else reading this mailing list, help
in testing would be much appreciated. If I succeeded in not breaking
anything, then I'll patch the program with this change after a short
period of testing.
///begin code
function edit_field_in_external_editor (buffer, elem, doc) {
if (! doc) {
if (elem instanceof Ci.nsIDOMHTMLInputElement) {
var type = (elem.getAttribute("type") || "").toLowerCase();

throw interactive_error("Element is not a text field.");
} else if (!(elem instanceof Ci.nsIDOMHTMLTextAreaElement))
throw interactive_error("Element is not a text field.");
}
var name = get_filename_for_current_textfield(buffer.document, elem);
var file = get_temporary_file(name);

elem instanceof Ci.nsIDOMHTMLTextAreaElement)

var content = elem.value;

content = elem.innerHTML;
