Zindus is a new Thunderbird extension which can synchronize your Google Contacts with Thunderbird's Address Book.

Since Thunderbird and Google Contacts uses different fields, Zindus doesn't support importing entire Google Contacts into Thunderbird. Instead, these are the fields that you can safely sync across:

1. Full Name
2. Primary and Second Email address
3. Phone Numbers: Home, Work, Work Fax, Pager, Mobile
4. Instant Messaging (AIM)
5. Company and Title
6. Notes

Currently, mailing lists are not supported.
