--- Comment #3 from Ashish SHUKLA <ashish@FreeBSD.org> ---
I believe this commit[1] broke Firefox on Wayland:

shm_open("/wayland.mozilla.ipc.0",O_RDWR|O_CREAT|O_EXCL,0600) =3D 31 (0x1f)
shm_unlink("/wayland.mozilla.ipc.0")             =3D 0 (0x0)
mprotect(0x91c3c818000,4096,PROT_READ|PROT_WRITE) =3D 0 (0x0)
posix_fallocate(0x1f,0x0,0x4)                    =3D 19 (0x13)
close(31)                                        =3D 0 (0x0)
SIGNAL 11 (SIGSEGV) code=3DSEGV_MAPERR trapno=3D12 addr=3D0x0
mprotect(0x91c3c818000,4096,PROT_READ|PROT_EXEC) =3D 0 (0x0)
sigprocmask(SIG_SETMASK,{ },0x0)                 =3D 0 (0x0)
unlink("/tmp/firefox/lock")                      =3D 0 (0x0)
close(13)                                        =3D 0 (0x0)


It segfaults at the startup due to posix_fallocate on a ZFS root
(/wayland.mozilla.ipc.0), which seems to be the change in the referenced
commit.

I'm on 12.1-RELEASE, and downgraded back to 77.0.1_1,1 for now, which works
fine.

Thanks!
