I have www.example.com which loads a script like
<script src="external-url.js" async deferer></script>
This script has
var nameVariable = true;
How could I get the value (if it exists) in a popup.js of chrome extension?

Something like [Access global js variables from js injected by a chrome extension](https://stackoverflow.com/a/46870005) - the second code snippet is what you put in the popup script. – wOxxOm Feb 23 '18 at 10:56

Well, I can't help you without knowing what are the errors. See also the [extension architecture](https://developer.chrome.com/extensions/overview#arch). – wOxxOm Feb 23 '18 at 12:35
