I like Thunderbird for my email along with plain text. I disabled HTML emails and generally write most of my stuff in markdown anyway. So I'm looking for a way, to get Thunderbird to display markdown formatted plain text mails nicely when I view them.
I know Markdown Here. It's nice. But it renders plain text mail in markdown format to HTML. That's not the way I want to go: I want to avoid HTML mail and stick with plain text instead.
I just want Thunderbird to show my mails in a nice format when I'm viewing them — like with headers, lists, emphasis, links and of course code snippets.
