Firefox in the default DispVM displays a post-crash error message

... which looks pretty inelegant. Shall we extend the dispvm savefile creation timeout to ensure clean FF exit?

Most likely it will not help. We need clean shutdown of firefox (and others) rather than simply killing Xorg...
Relevant file is core-agent-linux/misc/dispvm-prerun.sh.

firefox can be "gracefully killed" via xkill:

xkill -id $(xwininfo -root -children | fgrep '"Navigator"' | awk '{ print $1 }')

but it must be done from inside the VM, xkill from dom0 kills guid

That script I've pointed is running inside of VM.

Hmmm, can we just kill all windows before killall Xorg in core-agent-linux/vm-systemd/prepare-dvm.sh?

xkill wasn't enough - Firefox still handled that as crash. No surprise - xkill forcefully terminate x11 connection to particular client (XKillClient call).
Done by sending proper WM_DELETE_WINDOW message - same as window manager in response to "close" button of window decoration.
