gContactSync has been great, hence the five-star review. Sadly, Thunderbird disabled it with one of their updates, without warning, which finally prompted me to ditch Thunderbird after at least ten years of use. Shame on you, Thunderbird.
I am now a VERY happy user of em Client. Seamlessly deals with Google contacts (and Exchange contacts, for that matter), plus it has a much more modern and pleasing UI. I had to give up a grand total of nothing to make the switch fro Thunderbird to em Client. Highly recommend to frustrated Thunderbird users.
