I did build firefox from sources (several times since 3.6.10) and it was
not requiring these...
Is it the new 4.0 version ?
Regards,
Guido

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.

Do you have more info on these? Such as what files and sockets are
being managed?

The mozilla_tmp_t is used by firefox to create
/tmp/plugtmp/plugin-crossdomain.xml (for instance while viewing Youtube
streams).

These ones I have not been able to hit immediately, but I'll run a while
without to see if I can get the information back.

Not anymore apparently. Been running now for quite some time without these
privileges and I get no problems with it. Retry:
Mozilla/Firefox creates temporary files for its plugin support (for instance
while viewing flc streams), like /tmp/plugtmp/plugin-crossdomain.xml.
Update policy to allow it to create its own tmp type and perform a file
transition when creating a file or directory in a tmp_t location (like
/tmp).
