Message: ReferenceError: `Components` is not available in this context.
Functionality provided by Components may be available in an SDK
module: https://developer.mozilla.org/en-US/Add-ons/SDK

However, if you still need to import Components, you may use the
`chrome` module's properties for shortcuts to Component properties:

Shortcuts:
  Cc = Components.classes
  Ci = Components.interfaces
  Cu = Components.utils
  CC = Components.Constructor
Example:
  let { Cc, Ci } = require('chrome');
