*Only the first (primary) attribute of each type is synced from Google unless otherwise noted. The others are preserved while updating a contact.

**The attributes marked with ** are not standard in Thunderbird and are added by this extension to the Address Book.

gContactSync is not able to synchronize the custom fields in Gmail and Thunderbird together due to limitations in Google's API.

All local data that is not synchronized (for example, extra e-mail addresses in a Google Contact) is preserved.
