improvement proposal Rated 3 out of 5 stars

Hello Josh,
I better understand the problem ...
Example:
I create in thunderbird an address book on 01/01/2016, named "contact_on_THUNDERBIRD"
I create in google an address book on 01/01/2016, named "contact_on_GOOGLE"
Each book is empty contact.
I made synchronization with gcontactsync: no soucy
I create a "amigoTH" touch in "contact_on_THUNDERBIRD"
I create a contact "amigoGO" "contact_on_GOOGLE"
I made synchronization with gcontactsync: no soucy, each contact is copied on each side.
BUT, if I move OR copy a contact (eg old_amigo) created before 01/01/2016 another Mozilla Thunderbird address book, to the book named "contact_on_THUNDERBIRD"
AND that syncs,
THEN this contact (old_amigo) will be DELETED from the book named "contact_on_THUNDERBIRD"
This is true for all options!
I tested everything :)
I have not tested to the same case in google.
Could you, please you, to everyone who uses MOZILLA THUNDERBIRD as the source,
create a function in addition to notebooks, "raw copy"?
She would do to:
- Erasing all the contacts on the selected book Google.
- And then copy all the contacts of the book Mozilla Thunderbird to Google.
Thank you in advance for your enthusiasm.
I blot my previous post :)
Best regards.

Not working for me, and no forum support Rated 1 out of 5 stars

Despite the pleas to post questions and requests for help to the forum, I've only heard crickets there. The FAQ doesn't offer much troubleshooting help, either. It looks like a well-polished add-on, but it seems it just plain doesn't work, at least for me, for some reason. I'll happily change this review if I get any helpful assistance.

Good Add-On Rated 5 out of 5 stars

This is good add-on. But I found bug?:
I have website in Work tab. After editing website in Google and syncronization, Add-On deletes it from Work Tab and fills Private Tab. Is it normal behaviour?

This review is for a previous version of the add-on (2.0.8). 

That's expected (though unintuitive) behavior. Google has types/labels for websites while vanilla Thunderbird just has a work and home website. To allow synchronizing all different website types/labels gContactSync adds a drop-down to the TB work and home website fields and syncs the first two websites of any types with these fields.

The work tab has the second website field, so if you sync to Google it is added as the first and only website. If you sync back from Google Thunderbird syncs the first website with the home/private field and removes it from work.

Only syncs two emails Rated 3 out of 5 stars

This add-on works, but for some reason it only syncs two email addresses, this is not well-indicated in the app, and you cannot change this in the settings. Not very useful for business users.

This review is for a previous version of the add-on (2.0.7). 

This is a limitation of Thunderbird, not gContactSync. It actually syncs 4 e-mail addresses: the two included in Thunderbird and two additional e-mail addresses that gContactSync adds. When I started working on this add-on there was a feature request for TB to add support for n phone numbers, e-mail addresses, etc. but it was never finished.

Read only not working Rated 1 out of 5 stars

I just installed this extension. Because I was using an old extension to sync I already have a lot of Google contacts in my Thunderbird address book. I tell gContactSync to work in read only mode, only download from Google, when I do first time setup.
Now I have hundred of contacts duplicated in my Google account :(

This review is for a previous version of the add-on (2.0.7). 

Merge support is experimental, though it works pretty well if your contacts have names and e-mail address fields filled in. Could you e-mail me with more details?

In the meantime Gmail has an excellent tool for removing duplicates. If that doesn't work you can revert your contacts to before the dups were made and sync with an empty address book.

EDIT: Read-only mode applies only *after* the first sync. Otherwise your contacts from TB wouldn't be sent to Google during the initial sync.

Funziona benissimo! Rated 5 out of 5 stars

RAM hog issue on Mac Rated 3 out of 5 stars

I'm running iMac, 10.9.x. I have Thunderbird 38.2.0 so Google Contacts doesn't work anymore (it was working fine up until the last upgrade). So I DL'd gContactSync. It seemed to be working but now it seems to be a RAM hog in that when I have it loaded, it uses over 2 GIG of RAM. I disabled it and Tbird is back down to 360MB RAM. I'll go into my gmail and merge contacts as I noticed before using gContactSync that gmail would end up with thousands of the same duplicate email address, so not sure what was going on there...

Good but problem with google apps contacts directory Rated 4 out of 5 stars

Eveything is running perfectly except synchronisation with the directory we shared in our company, witch is just not present in thunderbird. Any idea of what's the problem ?

Works great in Win8.1. Using Linux (Kubuntu 15.04) with the latest Thunderbird only seems to work in the beggining, but syncing does not work. Sad for me, since Linux is my main system, and I use Windows just from time to time. So maybe once per week now to sync new...

Add-on is removing my contacts added via mobile device during sync on Thunderbird (on PC). Tested this incidence happening several times so confirmed on it. Disappointing. Removed.

Très utile Rated 5 out of 5 stars

Fonctionne très bien, mais prévoir une courbe d’apprentissage et quelques tests pour vérifier que tout fonctionne correctement (faire un backup de vos contacts au cas où!). Manque une traduction française et une meilleure documentation.

Great support. My problem is that I kept seeing the "First sync....merging contacts" and it never went away. So I asked for help and this solved it:

Thanks for contacting me first :). It sounds like you probably ran into an error which caused gContactSync to stop trying to merge contacts (the status bar contains the last message it displayed).

Could you go to gContactSync -> Preferences -> General and make sure "Log errors in the Error Console" is checked? If it isn't, you will need to check it, click OK, then restart Thunderbird and try to sync again.

Next, go to Tools -> Error Console. Click on the Errors tab. If you see anything with "gcontactsync" please right-click each one and click Copy, then paste in an e-mail to me.

Also, please click on "First sync...merging contacts" then copy/paste the very start of the log where it shows preferences/settings and all address books, and the bottom of the log.
