Control: found -1 68.11.0esr-1 Firefox on the latest version of testing still doesn't detect my laptop's mic. Seems like this is only a problem for systems without PulseAudio. I was able to workaround this problem by wrapping firefox-esr around apulse, but I'd rather have a true solution than a hack like apulse.
Students like me are going online for our classes, and it sucks that Firefox out- of-the-box won't detect our microphones. So please fix as soon as possible. Job Bautista
