Firefox currently supports an old version of RTCRtpSender.getParameters() and RTCRtpSender.setParameters(), which has changed significantly in more recent versions of the webrtc-pc spec. The most important change is the introduction of a transaction model, wherein setParameters() can only be called with the results of the most recent getParameters() call, with the desired modifications.
This change is not backward compatible with the present implementation, because the webrtc-pc spec has changed in a non-backward-compatible way. It is likely that existing code using RTCRtpSender.setParameters() will need to be updated to work with the new version of this API.
