I can’t play audio on a Remote Desktop Connection

If you are on a Remote Desktop Connection (RDP) on Windows, audio playback will be disabled due to increased security restrictions. This is a known issue since Firefox version 56 that we are working hard to fix.

In the meantime, you can reduce the sandbox security level by following these steps:

  1. In the address bar, type about:config and press EnterReturn.

    • The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise!I accept the risk! to continue to the about:config page.
  2. Search for security.sandbox.content.level, double-click on the preference and set its value to 2.
  3. Restart Firefox on the remote device.
