Review for Google Contacts by McCaan
Rated 4 out of 5 stars
I think that this is one of the most util add-on I've ever sync, and sould be incredible if could work together with MoreFunctionsForAddressBook for a full sync, with photos, extra phones, etc ...
This review is for a previous version of the add-on (0.2.90).To create your own collections, you must have a Mozilla Add-ons account.
