Markdown to JIRA од Paolo Antinori

Markdown to JIRA is just a tiny wrapper around j2m http://j2m.fokkezb.nl/, a javascript library that converts Markdown to JIRA markup (and the other way around) that does all the work.
It's inspired by the much more powerful Markdown Here http://markdown-here.com/ extension, that converts Markdown to HTML (I use it for Gmail).

This extension adds an entry to your right-click menu, called JIRA Formatting that expands further in 2 entries:

- MD to JIRA
- JIRA to MD

When you right click on an issue page on JIRA, and select one of the 2 functionalities, the extension will replace the content with the equivalent markup.

The addon has been tested on the following domains:

- *.jboss.org
- *.apache.org
- *.jira.com
- *.atlassian.com

But you can define in preferences on which domain you want it to be enabled.
