This add-on for Firefox will dynamically renders pages written in raw markdown (.md) into HTML. Supports the variation of markdown syntax used on GitHub.
Here is more about the add-on from the developers:
This add-on will modify the display of all server responses (or local files) that satisfy all of the following criteria:
- the HTTP header ‘content-type’ is either:
- the location protocol is not ‘view-source:’
- the location pathname ends with either: (md|markdown|mkd|mkdn|mkdown|rmarkdown)
