==Reporting WebRTC Call Issues==
[https://firefox-source-docs.mozilla.org/contributing/debugging/debugging_webrtc_calls.html Moved Here]
The best way to report an issue is through Bugzilla using this [https://bugzilla.mozilla.org/enter_bug.cgi?product=Core&component=WebRTC link]. Describing the issue you've run into, and include a URL along, with the details of the call setup.
 
For simple issues, the first place to look is to check the [https://firefox-source-docs.mozilla.org/devtools-user/web_console/ web developer console] for error messages related to media format issues. If you see messages here related to WebRTC, getUserMedia, or getDisplayMedia, please add this information to your bug.
 
'''Share Your about:webrtc Contents'''
 
# While your call is still ongoing, open a tab and visit about:webrtc<br />
# Click "Clear History" to clear the stats from other recent calls which are no longer ongoing.<br />
# At the bottom of the page click 'Save Page', and save this file.<br />
# Add this file as an attachment to your bug.<br />
This file contains statistics about your call, the signalling that was used to setup your call, and information about the network transports.
 
==Logging==
Logging can be enabled through the "Enable WebRTC Log Preset" button at the bottom of [about:webrtc]. Alternatively one can set the following environment variable:<syntaxhighlight language="shell">MOZ_LOG="jsep:5,sdp:5,signaling:5,mtransport:5,RTCRtpReceiver:5,RTCRtpSender:5,RTCDMTFSender:5,VideoFrameConverter:5,WebrtcTCPSocket:5,CamerasChild:5,CamerasParent:5,VideoEngine:5,ShmemPool:5,TabShare:5,MediaChild:5,MediaParent:5,MediaManager:5,MediaTrackGraph:5,cubeb:5,MediaStream:5,MediaStreamTrack:5,DriftCompensator:5,ForwardInputTrack:5,MediaRecorder:5,MediaEncoder:5,TrackEncoder:5,VP8TrackEncoder:5,Muxer:5,GetUserMedia:5,MediaPipeline:5,PeerConnectionImpl:5,WebAudioAPI:5,webrtc_trace:5,RTCRtpTransceiver:5,ForwardedInputTrack:5,HTMLMediaElement:5,HTMLMediaElementEvents:5"</syntaxhighlight> Note that webrtc_trace will not be active until "Enable WebRTC Log Preset" is pressed.
 
==Profiling==
One can use the "WebRTC" preset on the [about:logging] page with the [https://profiler.firefox.com/ Firefox Performance Profiler].
