# Firefox's Markdown Viewer

This morning, I’ve found a Firefox Add-on called Markdown Viewer. As its name suggests, it’s a Firefox plugin that enables users to view Markdown documents. The screenshot provided on the home page of the add-on illustrates that it works on M\$ Win*. How about GNU/Linux? I clicked the button and installed the plugin. After that, I used :restart in Vimperator to see what happened if I used Firefox to view a local Markdown file with extension name .md.

It turned out that nothing happened! With Lai’s review titled Work on Linux, I figured out what to do. After looking at his suggested code for vi ~/.mozilla/firefox/*default/mimeTypes.rdf, I really tested it and it worked. Critical readers will then ask about the way to include multiple file extensions.

Browsing the code with # in the RDF file helps. Here’s what my results.

According to a question on Super User, we use more than one extension name for a Markdown file. However, a GNU/Linux user should never use .md.

Finally, combining Lai’s and Cas’s posts, I’ve come up with a Gist.
