This occurred due to not having a page https:/ page loaded or reloaded in another window, which is necessary when performing the content script actions. The "TypeError: CONTENT_SCRIPT_PORT is null" was received in the console.
What the error, TypeError: CONTENT_SCRIPT_PORT is null means:
Make sure you have an http(s):// page loaded in a tab (e.g. https://www.mozilla.org/).
If the extension has restarted (e.g. disabled/re-enabled, reloaded…) since the page was loaded, you may need to reload the page.
