Publisher review:Google Contacts is a Thunderbird add-on that enables you to access your Google contacts and synchronize them with your Thunderbird address books.
Google Contacts lets you access bi-directionaly to Google contacts via address books. Google Contacts 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.
The Google Contacts addon is cross-platform and it works on Mac OS X, Windows and Linux.
Requirements:
- Thunderbird 3.1 and later
Operating system:Mac OS X 10.0 or later
