Excellent and super useful plug-in that I've used for years. It just got better as the developer greatly reduced required browser permissions.

Works on gmail for what I need: links, formatting, code blocks, lists and bullets

This extension just _saved my life._ My brain has apparently shifted to typing **everything** in Markdown. Now I can even use my latent TeX knowledge $\forall x \in X, \quad \exists y \leq \epsilon$. And then a quick Ctrl+Alt+M and, _hey presto_, everything is beautiful[^1] and all is right with the world. And it works in any website that allows "rich editing", not just in email!

Unfortunately, it turns out addons.mozilla.org only allows plain text reviews. Ah well, you'll just have to try it out on your own to see how great this extension is.

[^1]: Almost all. Apparently I'm used to Github Flavored Markdown which allows for footnotes, but Markdown Here does not yet support them.

Does what it is supposed to do. Helps with my mails. Back and forth conversion has its limits, but that is due to the limited but easy markdown format.

Ótimo! Vai facilitar muito minha vida

Works like a charm :-)

Working well for me so far in Gmail

This add-on is quite simply, brilliant. It lets you write Markdown in any text field that supports HTML/RTF.

I had been looking for a way to to work in Rally with Markdown and this was by far the easier option.

CTRL + ALT + M is now my favourite keyboard shortcut! Tables in Gmail are now easy!
