no longer working, unmaintained, no trust in developer Rated 1 out of 5 stars

Some time ago this was a pretty useful add-on, but for a while it does no longer work at all, as the user is asked for the Google contacts password in an endless loop.

No visible reaction from the developer despite numerous disastrous reports, so it seems that the application is no longer maintained. It was reported that the Google API that the add-on used (and which seemingly was now switched off) was marked as deprecated for years!

Besides the current severe problem this does not inspire trust that "simple" security problems would be handled appropriately, so even in case the app would be updated to work again I will longer trust my personal address book to this add-on, sorry.

Same here. Google API change. Rated 1 out of 5 stars

Login does not work. Google API change?

Rated 1 out of 5 stars

I used this plugin for a long time, but it stopped working the other day due to the changes in how Google is handling contacts and API access.

euromonkey - search for gcontactsync
That plugin does work and allows you to sync your contacts with TB even after the changes. I just installed it myself.

Does not work anymore. Google upgraded to OAuth2.0 and announced the change 2 years in advance. Google Contacts didn't stay current and won't work at all. I'll change my review when the issue is fixed. Appears the developer has abandoned the add-on which is a real shame since it worked great.

Keeps asking for password Rated 1 out of 5 stars

Looks like dont work the last days.

Does not work with Oauth token, so useless in state Rated 1 out of 5 stars

Was very useful.
Then Google set the Oauth token connection through all its services and many third party app's did not.

Other non recommended workaround is to lower down the security level of your google account.

Fix for Contacts password request is to disable google contacts add on and switch to google contacts sync add on. Works just fine now.

Password contact sincronize problem TB and Google contacts Rated 1 out of 5 stars

Since a few days ago, aprox. May 25th, TB keeps asking password to sincronize TB with Google contacts. Tried correct password, tried to delete account and renew password, and nothing...keeps with same problem. Seems that unfortunately this add on is not working anymore between TB and Google contacts.

Ne fonctionne plus depuis le 27 mai 2015 Rated 4 out of 5 stars

Très bonne appli, mais ne fonctionne plus depuis le 27 mai 2015. A chaque démarrage de Thunderbird, le mot de passe Gmail est demandé mais le saisir ne sert à rien, il n'est pas accepté. Est-ce dû à la nouvelle version du module contacts sur Gmail ? Quoi qu'il en soit, il est urgent de faire quelque chose car on ne peut plus utiliser Thunderbird dans ces conditions, surtout si comme moi on a une base unique de contacts sur Gmail, partagée avec Thunderbird et un smartphone Androïd.

Password Error since 27th May 2015 Rated 5 out of 5 stars

Was working great until now. Every time I restart Thunderbird, it prompts for password!!!!

password prompt since today Rated 5 out of 5 stars

This Add-on was very helpful and easy to use!
But I have the same problem with the password... always prompted for password since today because of API-changes. Is there any workaround?
Thanks in advance!

I'm experiencing the same password issue from today. Until this morning all was perfect.

Rated 1 out of 5 stars

I am facing the password-issue, too. Obviously the reasion for this is that the API used by this Addon is marked as depricated by Google since two years. And now Google switched off support for this depricated interface.
