enables 2-way sync of contacts between Google Contacts and Thunderbird. Must have for Android users who want fully-featured offline email app on PC while using Gmail address book. Slow but works great. Replaced not-so-good 3rd party integration tools via Outlook.

This review is for a previous version of the add-on (3.0.0).
