{
  if (ShouldResistFingerprinting()) {
    return;
  }

  nsIDocument* doc = GetResponsibleDocument();
  if (!doc) {

      orientation != eScreenOrientation_LandscapePrimary &&
      orientation != eScreenOrientation_LandscapeSecondary) {
    // The platform may notify of some other values from
    // an orientation lock, but we only care about real
    // changes to screen orientation which result in one of
    // the values we care about.
    return;
  }

  OrientationType previousOrientation = mType;
  mAngle = aConfiguration.angle();
  mType = InternalOrientationToType(orientation);

  DebugOnly<nsresult> rv;
