Soundcloud plays in mono using Firefox browser and Mac OS

System: MacPro 64GB RAM 3.5 GHz 6-Core Intel Xeon E5 running Yosemite 10.10.5 (14F2511)
Firefox version 60.0.2 (64-bit)

When using any other website including YouTube, google drive, Facebook, etc. sound is normal and plays in stereo through both the internal sound card and external Core Audio devices.

When using SoundCloud sound is in mono.

This does not happen in Safari or in Chrome.

Only Firefox.

Any ideas?

Hey @mikecrehore

I just tested on the same version of Firefox on High Sierra, and I don't have an issue there. Are you able to update MacOS?

I discovered the same thing!
Firefox 60.0.2 on Mac OS 10.12.6
Hi Tom,

Thanks for the answer. I am not able to update at this time due to other apps I am using for recording work, but plan to soon.
Has been resolved? Same problem here: MacoOS 10.12.6 and last firefox version
I am running OS 10.12.6 Sierra with Firefox 66.0.2 and all seems to be well at this point.
Having same issues for a while now, windows 10 and firefox 66.0.3
