On Fx81, we haven't enabled Media Session API by default yet, which would be enabled on Fx82. Could you try to enable that (dom.media.mediasession.enabled) and see if the issue gets fixed for you?
Thank you.

yessss that fixed the issue for me! :D Why wasn't that API enabled by default yet?

We wanted to ensure that media control can work well even if without media session API, so shipped them separately. But media session API would be enabled on Fx82 soon :)
