NO. That product has not worked for several years. Simple steps for a full backup are these:

1. ensure thunderbird is not running
2. enter %appdata% in search window on task bar and press Enter key
3. this should open windows file explorer in Appdata\roaming folder
4. highlight the Thunderbird folder and copy to external media

A comment: It is in a new beta, but it is not supported here. It may or may not work in the new beta, but even the developer advises caution. If you use it, I suggest extensive testing before placing trust in it. https://mozbackup.jasnapaka.com/support.php
