Synchronizes contacts between Thunderbird and one or more Google accounts. It can synchronize the My Contacts group, all contacts, or all contacts and groups (with mailing lists).
NOTE: Mailing lists are buggy, but gContactSync tries to work around these bugs whenever possible. By default 3.0.0 and later skip contacts without email addresses. If you change this the fake e-mail addresses [email protected] are necessary to prevent bugs in mailing lists and are only stored in Thunderbird (they'll never make it to Google). It is best to drag contacts into the main address book and add them to groups from Google's interface.
Please read the Developer Comments as well.
You may synchronize one account with several address books, synchronizing an address book with only one group of your choice, and can import contacts from Facebook and Twitter.<br>
If you choose to synchronize all contacts and groups don't try to delete or rename "My Contacts", "Coworkers", "Family", or "Friends" or you may have to 'reset' that address book. Google requires these groups for every account, including Google Apps accounts where you can't see them online.<br>
If you find a bug or have a question, please let me know about it. See the support information for the details.
Note: Mailing Lists in Thunderbird in Seamonkey are still somewhat buggy, especially when contacts are dragged and dropped into them. They don't work with contacts that don't have e-mail addresses, so gContactSync will add e-mail addresses like [email protected]
