    This feature is not on a current W3C standards track, but it is supported on the Firefox OS platform. Although implementations may change in the future and it is not supported widely across browsers, it is suitable for use in code dedicated to Firefox OS apps.

    This API is available on Firefox OS for privileged or certified applications only.


    The flashMode property value is a string that defines how the flash, if any, is to be used. When set, its new value must be chosen from the list of options specified by  CameraCapabilities.flashModes.


    var flash = instanceOfCameraControl.flashMode


    Return a string representing the current flash mode. The default value is auto if the device has a flash, none otherwise.


    var options = {
      camera: navigator.mozCameras.getListOfCameras()[0]
    function onSuccess( camera ) {
      var capabilities = camera.capabilities;
      if (capablities.flashModes.indexOf('off') > -1) {
        camera.flashMode = 'off';
    navigator.mozCameras.getCamera(options, onSuccess)


    Not part of any specification; however, this API should be removed when the WebRTC Capture and Stream API has been implemented.
