pkg_info -Dx firefox says:

If your Firefox crashes with the following message while viewing a
HTML5 page:
"Bad system call (core dumped)"

you need to load the sem module (kldload sem).

The page I was looking at was the default Google page. Firefox started
to crash after updating to 4.x - apparently, this option is not needed
for versions < 4.
