Extending Thunderbird mail client with Python

[John Bond]

Anyone have any experience with this, ideally using Python 3?

I'd like to sync my Thunderbird contacts with various things including 
my mobile phone. Of course, I want to do it with Python! I've seen some 
stuff around, eg. an XPI that provides Python bindings to the Mozilla 
XPCOM APIs (through which I imagine you can access Thunderbird data like 
its contacts database), but it doesn't seem maintained or ported to 
Python 3.

Cheers, JB
