Very useful addon, thank you!
I write emails faster and easier, and their appears more beautiful. :-)
Features I like:
- very nice rendering;
- support Github Markdown with syntax highlight in code blocks;
- dot not destroy your signature nor e-mails below your text;
- very easy way to switch between text and rendering.

Works on Thunderbird 45.2.0
