CloseReview for CardBook by Dark Steve
Rated 5 out of 5 stars
I'm *very* impressed by how well Cardbook works. This is a way better addressbooks system than the unmaintained legacy addressbooks Thunderbird has now.
The earlier reviews claiming it doesn't work are wrong or outdated, possibly referring to a bug in an earlier version (21.5?). I'm using 21.8 and it works great.
I was using Sogo Connector, but it was slow and buggy, and is barely maintained (if at all). For example, Sogo Connector would only sync the first two email addresses for a contact. Cardbook has no such limitations.
Cardbook should be bundled with Thunderbird by default (like Lightning), it's great and works perfectly with my Nextcloud setup.
