title: How to read/get information from live stream manifest
body: <p>Am running a drm widfine live stream and I like to get some information from the manifest. I found a website:</p>
  
  <p><a href="https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/runtime/getManifest#Syntax" rel="nofollow noreferrer">https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/runtime/getManifest#Syntax</a></p>
  
  <p>but if I run this code I get a: 'browser' is not defined  no-undef.</p>
  
  <pre><code>var manifest = browser.runtime.getManifest();
  console.log(manifest.name);
  </code></pre>
