Is there a way to change the playback device that firefox uses? I am trying to set the audio from firefox to a device that is not set to default. I cannot change that device to default, as it is being used by another program that requires it to be the default.

I understand that previous versions of firefox had user created add-ons to solve this problem, but they are not compatible with the newest version of firefox. The third-party solution that I have found for other apps, does not work with firefox or the other program than I am wanting to have on separate audio devices.
