Headphones not working with Firefox and only Firefox

1) When I played a video on Youtube with Firefox via my computer speakers, they worked flawlessly. 2) Then I plugged in my headphones via the headphones jack, there is no sound. 3) I went to Windows settings and checked the volume mixer and tested the sound, the headphones worked. 4) I opened Edge and played a video on Youtube, the headphones work flawlessly. 5) I played a video through my media player, the headphones work flawlessly.

So my conclusion is that it is Firefox that is broken.

I closed Firefox and restarted it and tried steps 1 to 5 above, still got the same results. Firefox did not play any sound over the headphones while all the others worked flawlessly.

I restarted my computer and tried the steps again and still got the same results.

I also deleted Cookies and Site data from Firefox settings and still no luck.

Any suggestions?

Oh I just figured out the problem, which lies in the Windows Volume Mixer. Somehow, it decided to mute the headphones through Firefox. I have no idea how that happened since I didn't know about the Volume Mixer before and definitely didn't mess with it. But I am glad the issue is fixed.

Thank you for the support!

Does it work if the headphone is plugged in before you start Firefox ?

For me, Firefox always uses the default output device for Windows, which I can select using a little speaker icon at the right end of the Taskbar near the clock. I'm not aware of a way that you can change that selection from within Firefox itself or for Firefox only.
