That directory is out of date. (I'm not sure why it hasn't been removed yet.) The new project page is here: https://github.com/mozilla/narcissus

We moved it to GitHub to make it easier for people to submit pull requests and the like.

Arh! I see.

So, when if I install this extension, I can hack those files (in the extension's directory I assume) reload the browser and the javascript engine will do whatever I have changed?
