Make sure you're setting host permissions in your extension manifest:

For a packaged app, you can do ajax requests without running into the cross-site access restrictions. I'm not 100% sure that it is needed, but if you are still having trouble, then make sure you add http://*/ to your permission section in the manifest (or restrict it further if you only need to make calls to certain sites). For hosted applications, you can not do cross-site requests without either a cooperating server (which specifically allows it), or using a proxy on your own server.

To get around the cross-site the best option (IMHO) is to write a web-service call to handle the request, then call it from your jQuery call. But if you can't write a web service to handle in a bit bigger pickle.
