No, it doesn't.

%pwd
/usr/lib/alsa-lib

%ls
libasound_module_ctl_pipewire.so  libasound_module_pcm_pipewire.so
%

Should I have it?  

Oh, good thinking.  You probably identified how I can avoid the crash.

Interesting---I don't know what I did here, but Firefox still crashes
when I keep device 2 in my .asoundrc, but I don't see the error message
above any longer.  The error I now see is below.  (Removing my .asoundrc
completely means I don't listen to audio anymore, but Firefox doesn't
crash anymore.)

(*) The new error when Firefox crashes

ALSA lib confmisc.c:165:(snd_config_get_card) [error.core] Cannot get card index for 2
