It works, but only one way. :(
It will update contacts from Google account to Thunderbird, but if you edit them and try to sync to Google, it will restore old data from Google account and erase edits done in Thunderbird. :( :( :(
No idea how to fix this...
This is TbSync, the manager UI, it does not sync. Please remove this review and add it to the sync provider you are using. Probably google-4-tbsync.
