The reason is that in VCF the first 2 fields are used for `P.O Box` and `Extended address`, respectively. Even if the `MozContact` API is a subset of VCF, it deliberately omitted these fields (as pointed out in https://wiki.mozilla.org/WebAPI/ContactsAPI). That's why the parser ignores these first two values. Not really elegant, I know :sweat_smile:

I'm open to suggestions to make it nicer.
