How to integrate Gnome Contacts with Thunderbird?

I have contacts in Gnome Contacts and I want to integrate/sync them with Thunderbird.

How do I integrate Gnome Contacts with Thunderbird?

Note: Due to the replies received, I should mention that this issue is not related in any way with Google contacts but with Gnome contacts.

Solution 1:

A cloud workaround: I'm using Thunderbird 68.7.0 (64-bit) on Ubuntu 18.04, with the CardBook extension, version 43.9, to sync with a nextcloud provider. Since I've registered my nextcloud account in the system settings, Gnome Contacts allows me to sync with my nexcloud contacts as well. Synchronization isn't lightning fast, but for contacts, that's not a problem to me.

Solution 2:

Gnome Contacts is the GUI frontend that works with Evolution Data Server. You can perform more advanced tasks on contacts in Evolution and it will show up in Google Contacts.

Export the addressbook from Evolution

• To export a complete address book, click File ▸ Save Address Book As vCard.

Then import the addressbook in Thunderbird

• Click on Address Book click Tools ▸ Import and then choose the option address book and select the previously exported file.
