title: "No 'Access-Control-Allow-Origin' header is present on the requested resource."
body: <p>I already tried looking for various questions, but that didn't help/I am too inexperienced to understand, so I have to be specific.
  This is what I get in the console:</p>
  
  <p>XMLHttpRequest cannot load <a href="https://a.websight.com/file/hex.json" rel="noreferrer">https://a.websight.com/file/hex.json</a>. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'chrome-extension://asdfghetcetcetc' is therefore not allowed access. (index):1</p>
  
  <p>It's breaking my entire extension and I don't know how to fix it. I would appreciate any help.</p>
