Rated 5 out of 5 stars
Such an amazingly simple to use extension! I love it! Can you get it to work with version 78 of Thunderbird? It's so useful to me.This review is for a previous version of the add-on (220.127.116.11).
There is a new version supporting Thunderbird 78 in review by Mozilla.
It is now at GitHub https://github.com/nattoheaven/macrotemplate.
