firefox audio plays audio on non-bluetooth device
Firefox plays audio (eg. of youtube videos) on the motherboard sound device even if there is a bluetooth headset connected via bluetooth USB dongle. Microsoft Edge and VLC plays audio on bluetooth video any user intervention. The win10 mixer shows that firefox is playing on audio on the non-bluetooth device and doesn't on bluetooth. I can't find a setting in Firefox to change this.

correction: Microsoft Edge and VLC plays audio on bluetooth device without any user intervention...
I would like to solve it without clearing cache or cookies or reinstalling Firefox.
