I haven't paid much attention to avc warnings.
did /.autorelabel, reboot, to see if that could stop avc.
Still see 'avc: denied' in auditlog, involving firefox,
plugin-config,...
last 6 of # grep -n avc audit.log:

no 'file_t' seen:
[root@f14 audit]# grep file_t audit.log [root@f14 audit]#
I have put only minimal effort into learning selinux syntax,
methods. Overwhelming, to me.
are there simple rules on how to respond to 'avc denied'?
If I do nothing?

Interesting AVC's. SEtroubleshoot is trying to figure out why a
certain application required execstack privs. In this case
plugin-config. It looks like you have installed an application plugin
for firefox that requies execstack. setroubleshoot was trying to
figure out if you had any libraries labeled as requireing execstack by
executing
ldd plugin-config.
Sadly this generated additional AVCs.
The setroubleshoot avc's are fixed in F16.
