- {{domxref("RTCDataChannel")}} instances are now [transferrable objects](/en-US/docs/Web/API/Web_Workers_API/Transferable_objects), and hence can be passed to [workers](/en-US/docs/Web/API/Worker). ([Firefox bug 1209163](https://bugzil.la/1209163)).
- The [`closing` event](/en-US/docs/Web/API/RTCDataChannel/closing_event) and the `onclosing()` event handler are now supported on the {{domxref("RTCDataChannel")}} interface. ([Firefox bug 1611953](https://bugzil.la/1611953)).
- The {{domxref("MediaDevices/getUserMedia","getUserMedia()")}} and {{domxref("MediaDevices/getDisplayMedia","getDisplayMedia()")}} methods of the {{domxref("MediaDevices")}} interface now support the [`resizeMode`](/en-US/docs/Web/API/MediaTrackConstraints#resizemode) constraint.
This constraint allows developers to request video that matches other constraints, such as resolution and frame rate, even if the requested constraints are not supported by the underlying hardware.
The browser may then crop, downscale, or reduce the frame rate of the video captured from a camera, or downscale (but not crop) the video captured from a screen or window. ([Firefox bug 1286945](https://bugzil.la/1286945)).
