  var DIGITAL_CLIMATE_STRIKE_OPTIONS = {
    /* The Tor website base URL */
    iframeHost: 'https://www.torproject.org',
    /* Disable Google Analytics, for user privacy */
    disableGoogleAnalytics: true,
    /* Let users dismiss the banner, and use the Tor website */
    showCloseButtonOnFullPageWidget: true,
  };
