Works like a smooth running train. Worked at once, no difficult settings at all. No duplicate contacts. Most likely older versions. Must say had all contacts in google contacts, none in Thunderbird yet.

It mainly works but is buggy so make sure you have a backup strategy. I got caught out by a problem I didn't notice for greater than the google 30-day backup period :(

I had to stop using this add-on because of the duplicate contacts issue others had mentioned. It created thousands of duplicates. I had to force-quit Thunderbird and restore my contacts from a previous date in the Google Contacts web interface (find/merge duplicates didn't work).

This addon creates duplicate contacts. I had over 500 of the same contacts on my contacts list.

Folks, this is the dogs knees when it come to google contacts and T'bird. Complex, but life is - and google even more so. Set it up right and you're away laughing!
Keep up the good work,
Morgan.

Looks like every Contact created after installing this Update got duplicated about 3000 times. Total Contact list was about 45000 contacts.

This is a great tool, if you want to freeze Thunderbird regularly and explode your address book! (Experience after several weeks)
Unfortunately even sync of partial changes doesn't work!

Recommend that you do not use this addon. It has a bug that creates multiple copies of your contacts - I had 24,000 contacts and it took forever to delete them all. The only thing that stopped it was that I'd hit the limit for contacts on Gmail - I had many many more in Thunderbird, slowing down the program considerably.

Google Contacts created a loop that generated 25,000 (really!) duplicate contacts in my gmail account. Even after I shut down Thunderbird, the process continued and I had to go into the Task Manager and kill the thunderbird.exe process to get it to stop.

The CPU Hog/Memory Leak issues that others described was the same for me. I've since disabled it (after isolating the problem) and we are back to normal. I'm using Thunderbird 9.0.1 (it happened in TB 8 too) / Google Contacts 0.6.40 on a 32bit Windows 7 machine.

Saved me so much time and effort importing my contacts from Gmail.
I was looking for a way to import my contacts to Thundderbord, since most of my contacts' names are in Hebrew. Gmail has trouble exporting contacts with Hebrew in them to an importable format for Thunderbird but this worked great! Thank you so much! Highly recommended...

It performs great! It is a very useful application. It fills the gap of IMAP standard not dealing with address lists. With the help of this program my contacts on my work and home computer plus my cell phone are always synchronized. (Before I had to it do manually by exporting/importing ldif files.) The differences in field contents of Thunderbird and on Google accounts are managed carefully. The only slight problem to me that the "display name" field that according Thunderbird sorts to is generated automatically in order <first name><last name>. If a next version may contain an option for the reverse order would be great.
Five stars plus one.

I have found Google Contacts Add On extremely useful. Along with Provider for Google Calendar the integration of Thunderbird, Google gmail contacts and Google calendar with my Android HTC EVO4G phone and my Desktop is complete.

Back in the day, when I had a PDA that couldn't make phone calls, and a phone that couldn't store (very much) data, I carried two devices with me (including a phone that worked for 3-4 days on a single charge), and synchronized my contact list by plugging my PDA into my computer, and running something like ActiveSync (Windows) or HotSync (PalmOS).... Then along came so-called "Smart Phones" (one of the most absurd misnomers ever), and "The Cloud" (the most insidious meteorlogical phenomenon since Hurricane Katrina). Now we are up the proverbial fecal matter-infested creek without a paddle.
Given the the general mess regarding database structure of the various systems of contact lists, I think the author of this Add-in has done a great job of trying to reconcile two distinct databases. The biggest complaints I have are against Mozilla, Google, and RIM, not the Add-on itself. I feel the industry needs to form Joint Contacts Expert Group to create a new ".JCEG" standard, that will enable consistency of database structure and terminology.
The synchronization of individual records works well, although not perfectly. Some contacts mysteriously do not synchronize... i.e. they are present in Google, but not in T-bird. The sync seems to have problems with records that are entered as company names (i.e. nothing in the "Name" field(s). I haven't yet been able to figure out why these problems pop up, but this is the only reason I give **** rather than *****.
However, It's the groupings that cause confusion. Formerly, I used Outlook "Categories" to keep my contacts separated into different groups, but neither Thunderbird, nor Blackberry, nor Mozilla uses categories (at least not in the user interface, although it MIGHT be present in the database itself (??). Now that I've ported my contacts over to Google, I have my ~1900 contacts broken out into different "groups", including one called "Active Contacts" and another called "Archive Contacts", etc. These are intended to be kept separate. Groupings of contacts are termed "Groups" in Gmail" and "Mailing Lists" in Thunderbird.... and these appear (in general) to be maintained during the synchronization, with a few limitations. Be aware that the Main group of "all" contacts for any mail service corresponds to an "unnamed" group in Google termed "All Contacts" (which you can actually view in the Beta version of Google Contacts, but not the normal view). Thus, all your Google contacts are synchronized, UNLESS you select just a single "Group" in the "Experimental" section of the Options for Google Contacts add-on. I haven't tried this features, as I need more than one of my groups to be synched.... so it's either all of them, or just one of them. It would be nice to be able to select multiple groups... thus another -1/2 star.
Now... Say you create a new contact in T-bird. Since there's no way to specify which group to assign it to, it will be part of your master list, but will be "unclassified". Somehow, the author of the add-on has devised to synch these to a group labeled "Other Contacts". Assuming you know to look for them there, you can then select the contact and decide which "group" you want it to be part of. This is very simple to do in Google, but not in T-bird, where you have to open the corresponding mail list, and add the new contact manually.... Not very convenient.
For BB users, a new contact created on your phone will be synched via GoogleSync to a Google group called "My Contacts". From there, you can add it OR MOVE IT to any other group you want. Once this is done, the "Google Contacts" add-on for Thunderbird obligingly syncs this to the "My contacts" mail list in Thunderbird.
All this is entirely undocumented, and it's taken me hours to figure it out.... but then, I seem to be spending most of my life recently trying to figure out how to make modern computer do what they used to be able to do much more simply and directly.
Bottom line is that this is an indispensable "leg" in my efforts to keep my contacts synched between the "cloud", my local email client (Thunderbird), and my Blackberry "smart phone". (read "idiot phone"). Given the impediments thrown up by competing forces in the computer industry, and unless and until Google offers mail clients for Blackberry and Windows (fat chance of that happening), this is the best we can do.

Wonderfull add-on. I wish photoes could also be syncronized

This review is for a previous version of the add-on (0.6.36). 

Photo is supported. Enable "Always reload contact photos" or use "Reload Photo" button in address book window. I recommend you to use the latter in the view of performance.

I like it! But now, it doesn't work properly since the upgrade to Thunderbird 6 - paradoxically fine in Windows XP, but not in Vista and 7. Any ideas?

This review is for a previous version of the add-on (0.6.36). 

I use it with Thunderbird 6 on Windows 7. So, it will be happened by another reason. Anyway, here is not a place to report a bug. Please add your issue to the following system and show me the detail.
