Yes, it looks like this is working again.

This one is working for me now too. It seems like livestreamfails has a transient issue with mp4s not being available over https.

Christoph, do you have any thoughts? Following bug 1633743, is there any action we should take when discovering issues like this in nightly?

Thanks for letting me know. At this point we are unsure when we are attempting to ship mixed content auto upgrading in release. For now, I'll just mark this bug blocking the pref-flip-bug-for-release (Bug 1672106). I guess marking issues blocking this bug is the way to go - thanks for asking.
