25 separate Mozilla Firefox instances in the Windows Mixer.

Why does FireFox do this? I only have three tabs open but there is 25 separate Mozilla Firefox instances in the Windows Mixer.

The only way to clear this is to reboot my computer. Firefox 72.0.1

I would hazard a guess that all those tabs have media, and Firefox is going to a process-per-tab (under some recommended limit) model. Firefox or windows or both are failing to free those controls instances (at least visually).

Seems possibly worthy of a bug report.
