My business site - www.ninjanezumiproductions.com - has videos on it.

Firefox PERMANENTLY MUTES those videos.

I can play them, but I get no sound.

I can play these videos on Chrome, Edge, Opera - etc... and still mute and unmute as normal.

However, when I try to UNMUTE on firefox, it prevents me.

This is harming my business.

I want to know how to fix this.

Sincerely,

Kevin Conner CEO: NNP, LLC

The audio format appears to be AC3 which is not a web standard and does not work in Chromium either: https://www.chromium.org/audio-video/

Try using a different audio codec that will play in all browsers: https://developer.mozilla.org/en-US/docs/Web/Media/Formats/Audio_codecs

Best is probably to use AAC for audio.

My audio codec is AAC not AC3. I have no idea why you think it's AC3.

However, I will recode in dolby digital just in case.

So yeah, I'm 90% certain you lied about it being AC3.

Both VLC and ffmpeg identify it as AC3.
