The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Thanks for reporting! To help diagnose this issue better, please can you:

1. Type "about:support" in Firefox and copy-paste its contents here
2. Capture a log when the issue occurs:

• In Firefox, ideally freshly started with no other tabs, go to about:logging in a new tab
• Select the Media preset
• Enable "stack traces for log messages"
• Click on "Set Log Modules"
• Click Start Logging
• Reproduce the bug
• Back on about:logging, click Stop Logging
• In the new tab that appears with the Firefox Profiler web application, in the top right click the button to upload the profile
• Make sure hidden threads are included and upload, then share the link here or send privately to a Mozilla developer
  -See https://paul.cx/public/about-logging-presentation.webm for a video walk-through

4. If this used to work in an earlier version of Firefox, please do a bisection to find the exact change that caused this (https://mozilla.github.io/mozregression/)
