Firefox and Thunderbird

Mozilla Add-ons site

Go to the Firefox Add-ons page for Markdown Here and install normally.

Or go to the "Tools > Add-ons" menu and then search for "Markdown Here".

After installing, make sure to restart Firefox/Thunderbird!

Note: It takes up to a month for Mozilla to approve changes to the Firefox/Thunderbird extension, so updates (features, fixes) will lag behind what is shown here. You can manually choose to install the newest version before it's reviewed from the list of versions: https://addons.mozilla.org/en-US/firefox/addon/markdown-here/versions/
