Any idea what might be going on?  Any hint how I could diagnose the problem?

I would start from comparison of "vainfo" output and related sections inabout:support.


ArchLinux and Debian wiki may give some troubleshooting hints
https://wiki.debian.org/Firefox#Hardware_Video_Acceleration

Internally Firefox likely uses a test like

    /usr/lib/firefox-esr/vaapitest -d /dev/dri/renderD128
