In a little more detail...

I create addons for Thunderbird, have served as a Mozilla addon editor in the past, and am currently a Thunderbird core reviewer.

Most of my addons consist of attempts to push Thunderbird in new directions, and frequently have required changes to the backend to allow extensions to do new things.

Most of my current effort is devoted to my ExQuilla addon, which adds support for Thunderbird to use Exchange Web Services to access email and contacts.

Add-ons I've created

ExQuilla for Microsoft Exchange

How to fix the core code Rated 5 out of 5 stars

As mentioned by others, this addon does not work with Thunderbird 38 due to an encoding issue. I've looked at the code, and presented the trivial change needed to restore read/write capability of template files. See http://mesquilla.com/2015/07/15/fixing-quicktext-addon-for-thunderbird/

I've contacted the author asking that this change be done, or someone else released to do the change.
