If user idles for a day without using firefox, then websites shouldn't be allowed to autoplay, until user uses Firefox again.

Do you mean the permission should be canceled after OS going to sleep mode? But the sleep mode might be triggered after just a few minutes, it seems to short. NI UX for the comment1.

Perhaps we could tie this to an OS shutdown/sleep mode. Currently, we use the session to reset the autoplay permission, adding the 24hrs rule is to address the users who never close their browser (especially the Mac user). We try to assign a timeout to the permission so they won't be surprised by the sound of the autoplay when they come back to the browser next day. I think OS shutdown/sleep mode does similar things here. If a user shutdown his/her computer, the browser session ends and the autoplay permission expired. If the user left for a while, the OS sleep, then the browser idle as well. The only differences is that we have more control to the perfer duration if we have our own timeout.

What problem are you trying to solve with the timeout?

We decided to not keep this behaviour.
