Rated 1 out of 5 stars

Hi *,
tried this add-on with Thunderbird 8.0 and found: while first synchronize all my Google contacts have been TRIPLED: from 440 to 1320 contacts, and the default groups like coworkers etc. have been doubled.
Next step was uninstall!

Sorry, good idea but seems to need more development.

Good luck for that, KH

This review is for a previous version of the add-on (0.3.4). 

Hello,

I do apologize for the duplicated contacts and groups. It's easy to undo recent changes if you go in Gmail and click on Contacts.

In the future I recommend you read the description of an add-on before using it, or at least before writing a review for it. That is a known "problem" that has been addressed in the development version available at the bottom of the page. I had the following text in bold in the add-on description well before you wrote this review, which should hopefully explain why you got those duplicates.
"When first setting up gContactSync 0.3 you should use a new address book. If you try to sync an address book with gContactSync that you already synchronized with a different add-on then you could get duplicates. 0.4 will merge contacts first."

Regards,

Josh
