I'm using Google-4-TbSync since a while and it just works.
On another thunderbird instance I managed to sync google contacts with thunderbird adressbook without any add-on and it seems to work, too. Here is the tutorial video: https://www.youtube.com/watch?v=vny1K_aUzCE&t=60s
I assume that it is possible with newer thunderbird versions and wasn't possible at the time Google-4-TbSync was initially developed.
Does the use of Google 4-TbSync have advantages over this? If not, my tendency would be to do without the add-on.
Thanks to the developers for the commitment and a response!
Thanks for Your review!
Yes, Google-4-TbSync also synchronizes groups, which seems to be impossible with CardDAV due to Google not properly supporting this protocol: https://github.com/zanonmark/Google-4-TbSync/wiki/Why-another-Google-synchronization-add-on
Thanks,
