Shorthand URL notations cause page freezes
Decentraleyes 2.0.0beta1 WebExtension on Firefox Nightly 2017-08-29.
If the CDN resource does not have explicit URL scheme (e.g. <script src="//code.jquery.com/jquery.min.js"></script>
), the page freezes.
Example: https://jsfiddle.net/xm1tza0d/3/ and https://xuhaiyang1234.gitlab.io/AAK-Cont/
