AFAIK that is not allowed.

Can you specify the type of resource you are trying to read?

If it is a script - you can load the script content into content script, and then add it using script tag by injecting it into DOM of page Script

//content scriptvar resourceData = self.data.load(NAME);
 var head = document.getElementsByTagName('head')[0];
 var script = document.createElement('script');
 script.type = 'text/javascript';
 script.innerText = resurceData;
 head.appendChild(script);

If it is text/xml/html/json - you can pass it using window.postMessage(). An example is shown here a link

You may also find it useful to write a method in Content script that listens for a message event in content script, and on receiving a message in content script from Page Script, you could post back to Page Script using window.postMessage() with the resource data
