Update 09-oct-2019 for v42.4: Just noticed that my addressbook is back -- thanks for the fix!
Cardbook now earns it's 5 stars again.

Used to be a very good plugin. But when upgrading Thunderbird from v60 to v68 (and updating the plugin accordingly), the entire addressbook vanished, and I find no trace of its database file. [based on v41.6]
