Google Contacts

Google Contacts is a Thunderbird add-on which allows you to access your Google contacts and synchronize them with Thunderbird address books. It detects gmail accounts which have already set up and creates address books for each of them.

Cards in the address books are synchronized with Google contacts; they represent the current Google contacts contents and Google contacts will be modified when you modify the cards. TB's mailing lists and Google's contacts groups are synchronized in the same manner.
