I have portable version of Thuinderbird and have deleted all my contacts from Thunderbird. After sync command nothing is imported and my address book in TB is still empty. On gmail I have more than 1000 addresses

This review is for a previous version of the add-on (1.0.0). 

Could you post on the forum with more details? http://pirules.org/forum/index.php

If you deleted all contacts from a synchronized address book gContactSync would have prompted you to delete all of them from Gmail since it is synchronizing the change you made. If you clicked Cancel then it would have disabled synchronization to let you manually resolve the issue.
