I had firefox crash on me but the core looks suspect. I don't understand
why `push %r15` is an invalid instruction.
% egdb /usr/local/lib/firefox/firefox ~/firefox.core

The firefox package is farily recent (though not current):
Sep 26 09:18:40 home pkg_add: Added firefox-117.0.1p0->117.0.1p0
The system is running a bit more recent snapshot:
OpenBSD 7.4 (GENERIC.MP) #1382: Wed Sep 27 10:51:31 MDT 2023
FWIW, the system is fairly old Ryzen 7:
