Firefox can fail to spawn child processes on the first launch. After being restarted it runs fine. Consider adding more swap space for stable Firefox work.

...

In some scenarios Firefox hangs or crashes. In many cases enlarging the swap helps. In the example below we enlarge swap from 4 to 8 GB:

$ zfs get volsize rpool/swap
NAME        PROPERTY  VALUE  SOURCE
rpool/swap  volsize   4G     local
$ pfexec zfs set volsize=8g rpool/swap
$ pfexec reboot
