I can install firefox in a 20.04 ubuntu image however I can't get the sound to come out to the host. I think it is because of these messages: oot@lnx01:/# firefox libEGL warning: DRI2: failed to authenticate ATTENTION: default value of option mesa_glthread overridden by environment. [Child 8724, MediaDecoderStateMachine #1] WARNING: 7fdc1c636ee0 OpenCubeb() failed to init cubeb: file /build/firefox-kPTBHF/firefox-128.0+build2/dom/media/AudioStream.cpp:285

I am using the tainted nvidia driver on my host. Has anyone got this to work? I messed around by adding various mesa drivers to the image with no fix. Any suggestions? I am using the ppa version of firefox in the container.
