Only Firefox doesn't see my microphone

Firefox seems to be the only application that doesn't recognize my microphone.  I can record audio with Audacity and set the recording levels in alsamixer, but on this laptop, Firefox doesn't give the option to share a microphone of any kind, as depicted below.  On other computers I have (also running Arch), the window will have a "Microphone to share:" dropdown below the "Camera to share:".

Any thoughts?  I'd be happy to provide more info/outputs to help give anyone a better idea of what's going on.

Re: Only Firefox doesn't see my microphone

Do you use plain ALSA without pulseaudio? Firefox has a strange policy of only using whatever is defined as hw:0,0 in a ALSA only case. Can you post

arecord -lL

and specify from which of the listed devices you'd like to play from?

Yes, ALSA without PulseAudio.  Is it normal for pulse to be listed below even when it's not installed?  Of the listed devices, "default" and "sysdefault" both work to access my mic.

$ arecord -lL
null
