I believe this is related to other topic that was discussed here, namely that you cannot get pointer to object properties. So there is no way how to get a pointer pointing to Form.LB.Browser.en_edit.FirstName.
As you noticed, you can still manipulate such form objects with commands that accept object name, but there are no such commands that would allow to get / set object value. What you maybe could do is, for example, is to use the same object name as is the property name, and then you could use Form[OBJECT Get name] := newValue but the generic method for properties like Form.LB.Browser.en_edit.FirstName would be a bit complex.
