You can load sem.ko to the same effect, FWIW.  The UPDATING entry for
firefox3-devel mentions this in the following part:

  20090628:
    AFFECTS: users of www/firefox3-devel
    AUTHOR: gecko@FreeBSD.org

    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).

    To load sem on every boot put the following into your
    /boot/loader.conf: sem_load=3D"YES"
