WFM. Can you reproduce with a new profile?
Yes. I was able to reproduce the issue in a new profile.

Do you have media.mediasource.enabled=TRUE ?
Yes I do. Setting media.mediasource.enabled=FALSE with media.mediasource.ignore_codecs=FALSE sometimes causes this crash, https://crash-stats.mozilla.com/report/index/794733cb-b870-47be-ae4c-d7c702140902 when attempting mp4 playback. When it doesn't crash, video playback is still blank. Setting media.mediasource.enabled=FALSE and unsetting media.mediasource.ignore_codecs (default states) also still results in blank video playback. As an aside, wouldn't that have been caught by using a new profile?
