An essential, excellent add-on. A big thank you to the developer for his ongoing work, keeping this updated and adjusted to the changes that newer Thunderbird versions enforce.

This review is for a previous version of the add-on (1.5).  This user has a previous review of this add-on.

Great add-on, works perfectly with Keepass-xc , allows you to fill automatically the master password (despite a recent little bug)

What is this for? There's no such plugin for Keepass called "KeepassXC"

This review is for a previous version of the add-on (1.0.3). 

It's for the password manager https://keepassxc.org/
If you are using KeePass2 you can use https://keepass.info/plugins.html#keepassnatmsg

A great addon for using passwords stored in KeepassXC directly in Thunderbird without the need to copy & paste them every time. It is as good as the KeepassXC extension in Firefox.
