Comment (by tom):

 There are two scenarios for this: Windows and Linux.  I understand Windows
 more.

 If you install Windows N or KN you'll be missing Windows Media Foundation
 and Firefox will detect that and prompt you here if you try to play
 something and can't: https://searchfox.org/mozilla-
 central/rev/403038737ba75af3842ba6b43b6e2fb47eb06609/dom/media/doctor/DecoderDoctorDiagnostics.cpp#682

 If you're on Linux and you're missing 'ffmpeg' you'll get a similar
 situation - but I don't understand all the details of what 'ffmpeg'
 entails. It appears there's code for that right next to the Windows one
 though so hopefully one can figure it out from that?

 In both cases, our telemetry indicates that the users who are in this
 situation is minimal: a few percent.

 I don't know if we can technically or legally bundle codecs with the
 browser in either case.
