Firefox Addon Scripting Trusted Page Content
Question
So I'm trying to use a chrome:// URI in my add-on and I want to use a page-worker on it using the scripting trusted content method, however it seems to not work when I hard code the URI in, the chrome://<package name>/<part>/<file> ; however, it works when I use the self.data.url('filename'). I want to use the chrome:// URI is because I use a GUID instead of the email style as the add-on's ID and also I don't want to use the resource:// URI.
Content Script
addon.port.emit('hi');
HTML
<html>
<head>
<meta charset="UTF-8">
<title>Gaia Utils Settings</title>
<script type="text/javascript" src="http://code.jquery.com/jquery-2.1.1.min.js"></script>
<script type="text/javascript" src="chrome://gaiascripts/content/dropdown.min.js"></script>
<script type="text/javascript" src="chrome://gaiascripts/content/settings.dev.js"></script>
<script type="text/javascript" src="chrome://gaiascripts/content/test.dev.js"></script>
<link href="css/bootstrap.min.css" rel="stylesheet" type="text/css">
<link href="css/settings.css" rel="stylesheet" type="text/css">
<link href="css/poststyle.css" rel="stylesheet" type="text/css">
</head>
<body>
<nav id="navbar_header" class="navbar navbar-blue navbar-static-top"></nav>
<div id="content_wrapper" class="container">
<div id="content_padding" class="container"></div>
</div>
<footer class="footer"></footer>
</body>
</html>
main.js
var PageWorker = require("sdk/page-worker");
PageWorker.Page({
contentURL: "chrome://gaiautils/content/settings.dev.html",
onMessage: function(message) {
console.log(message);
}
});
I know I can use a page-mod and attach the scripts to it with that, but I'd rather call the scripts from within the file and be able to communicate with the main add-on code. So is there a way so that I can have my cake and eat it too - using the hard coded chrome:// URI in conjunction with calling the scripts from within the HTML file while being able to have those scripts communicate back to the main.js file?

How can I have it so that I can use the addon.port.emit() in the content scripts that are called directly in the HTML file so that I don't have to use the self.data.url('htmlFile'), because I don't want to use the resource://pageckage-GUID-at-jetpack/path/to/file
The SDK only considers pages "trusted" if the URL you're loading is part of the add-on assets ( data/ ). chrome:// URIs are not. Hence you'll need to use regular content scripts via the contentScriptFile: [...] option in your PageWorker definition.
<script type="text/javascript" src="http://code.jquery.com/jquery-2.1.1.min.js"></script>
Don't ever load remote scripts for security reasons (and performance reasons to a far lesser extent)! Ship a local copy of jQuery if you want to use it.
