sockets are for pulseaudio and gconfd ( both of which i rather would
confine )

in my policy firefox is allowed to manage mozilla_tmp_t dirs files and
fifo files.

in my policy firefox does not need access to user_tmp_t content but that
is because i have almost everything confined here in f14. I am just
saying that its possible.

I have been using this policy for months now.
