Copy Thunderbird rich text HTML e-mail as Markdown

This Thunderbird extension does not exist and seems not to have existed. A whole bunch for copying as plain text?

Huh maybe what i really want is a GNU/Linux, Debian or Ubuntu Gnome or otherwise utility that takes rich text in the clipboard and pastes it as markdown.

Anyhow it’s something i’d like to find like three other people who want it and fund someone else to develop!

PWGD - people who want good deeds - no. good things. good demonstrably existing stuff?
