The sound has disappeared on Firefox but works with other browsers. Can anyone tell me how to fix this?

I was watching a video of a musician on YouTube and all of a sudden, there was no sound. I tried it using Chrome and had no problem. I refreshed Firefox, but still no sound. Can anyone help?

Check to see if volume is not turned down on the video. Then check to see if windows volume is not turned down. Last click the little speaker icon, select mixer, if you have that option and check to see if Firefox is not muted.
