I looked for firefox5 x86_64 and did not quickly find it, if you know
where there is a link, I will look into what is going on, otherwise I
will wait until Fedora Packages it.  It does seem strange that you are
getting those

 Permission audit_access in class sock_file not defined in policy.

errors, What OS are you using?  What kernel?


That was Scientific Linux 6, I was also running Tor (through openvpn), so that might have complicated matters.  I had also been messing around with Tor to get it to send all net traffic through tor, and the install was tainted at that point (I never was able to get that to work, similar SELInux audit errors to the above funnily enough).  I had also built and installed the latest kernel as I have to do to get my webcams working (2 cams I have do not work with the default RHEL6 kernel).

However I've just installed the Fedora security spin, should be an untainted install (I am 'under attack' here!), Firefox 5 likewise crashes, though with no SELinux audit messages in /var/log/messages as far as I can see (just a few 'received policyload notice' lines).

Likewise chromium grinds to a halt at the usual black background, no SELinux audit messages again, not even the 'policyload' notice ones (assuming I've got it set up properly to report them).
