Errors by css3-mediaqueries.js in Chrome and Firefox

Hi,

It turns out the version of css3-mediaqueries.js included in this theme causes many errors in . It appears some stylesheets are being blocked because of “No ‘Access-Control-Allow-Origin’ header is present on the requested resource.”

This is what I get in the Chrome console:

Would it not be better to just remove this script? There is already this in the head section:
