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 in
about: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
