Evaluating require("noscript.js"), specifically evaluating 

    Cc["@maone.net/noscript-service;1"].createInstance()

which is at the top of noscript.js, results in the following error,

    Component returned failure code: 0x80570015 (NS_ERROR_XPC_CI_RETURNED_FAILURE)
[nsIJSCID.createinstance]...

This is with the latest conkeror from git, and the noscript xpi from
https://secure.informaction.com/download/releases/noscript-2.6.5.6.xpi

I was just reading the noscript source code, and the way that noscript loads itself in other browsers
is somewhat more involved than just Cc["@maone.net/noscript-service;1"].createInstance().  Someone who
uses noscript might want to look into making noscript compatible with conkeror out-of-the-box, rather
than relying on this fragile glue code.
