This used to happen to me all the time a couple of years ago. Are you able to reproduce it consistently?

I've been seeing this bug for the first time in recent weeks, but unfortunately I don't have a method to consistently reproduce this bug yet.

actually I think I've found a more reliable way to reproduce the bug. When opening a video in Private Browsing, adding additional tabs, and then closing the tab containing the video, the audio from the video continues in the background despite the tab being closed. This also happens in normal (non-private) sessions, but at seemingly random times.

I'm hoping that the STR will help resolve this issue.

I cannot reproduce this issue both in provate browsing and non-private browsing.

I thought this might be related to bug 1344357, which leaks a window and the videos under it. 
However, it seems not, the audio stops when the leaked tab is closed in bug 1344357.

Per comment 5, 
I am going to close it. Please feel free to reopen it if everyone still can see it.

I've tried 20+ times, but still can't reproduce this issue on Nightlly 63.0a1 (2018-09-04) (64-bit) on OSX 10.13.5.

IIRC, cpearce discovered a root cause in another bug..

[Chris Pearce [:cpearce (Not reading bugmail)]]

I fixed one cause in Bug 1471800 which will ship in Firefox 63. There could be other causes.

Lets close this with the assumption it got fixed by bug 1471800. Feel free to re-open if still not fixed.
