CloseReview for CardBook by Ahnoold
Rated 5 out of 5 stars
This review is for version 73.3 on Thunderbird 91.4.1. This add-on works so much better than Thunderbird's built-in address book for the accounts that I connect to. Especially for connecting to my work's Office 365 account.
This review is for a previous version of the add-on (73.4).To create your own collections, you must have a Mozilla Add-ons account.
