  1. Ensure that you've enabled the extension developer features on the about:flags page in Edge.
  2. Open the "..." menu, click "Extensions", the cog icon next to Adblock Plus, then "Background page".
  3. Paste the above code in the background console which opened, and let us know what the output is.
