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

shm_open("/wayland.mozilla.ipc.0",O_RDWR|O_CREAT|O_EXCL,0600) = 31 (0x1f)
shm_unlink("/wayland.mozilla.ipc.0")             = 0 (0x0)
mprotect(0x91c3c818000,4096,PROT_READ|PROT_WRITE) = 0 (0x0)
posix_fallocate(0x1f,0x0,0x4)                    = 19 (0x13)
close(31)                                        = 0 (0x0)
SIGNAL 11 (SIGSEGV) code=SEGV_MAPERR trapno=12 addr=0x0
mprotect(0x91c3c818000,4096,PROT_READ|PROT_EXEC) = 0 (0x0)
sigprocmask(SIG_SETMASK,{ },0x0)                 = 0 (0x0)
unlink("/tmp/firefox/lock")                      = 0 (0x0)
close(13)                                        = 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!
