Review for gContactSync by glc25
Rated 1 out of 5 stars
Buggy. Do not use v. 0.2.17, except for manual synchronization
this add-on DOES NOT synchronize contacts automatically as it seems to be designed for, because the login and password used for Gmail accounts gets lost, showin a pop-up all the time, inviting to re-login every 2 minutes.
If this MAIN bug is solved one day, maybe this add-on will be usable adn will work as any other add-on connected to Gmail.
