User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:100.0) Gecko/20100101 Firefox/100.0

Steps to reproduce:

  1. Open Firefox
  2. Open new private window with ctrl+shift+p
  3. Watch any video (both Youtube or Vimeo)
    The problem only occurs in private windows.

Actual results:

Video playback repeatedly interrupts, while the audio keeps running unaltered.
After a while, video playback jumps to the state of audio playback and resumes in sync with the audio. The length of intteruption varies from less than a second to multiple seconds at a time.

Expected results:

No issues playing any video stream. Hardware and internet connection are sufficient, as the playback in non-private windows shows.

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.
