Description of problem:
SELinux is preventing /usr/lib/xulrunner/plugin-container from 'name_connect' accesses on the tcp_socket .

*****  Plugin mozplugger (89.7 confidence) suggests  *************************

If you want to use the plugin package
Then you must turn off SELinux controls on the Firefox plugins.
Do
# setsebool unconfined_mozilla_plugin_transition 0

*****  Plugin catchall_boolean (10.0 confidence) suggests  *******************

If you want to allow mozilla to plugin can network connect
Then you must tell SELinux about this by enabling the 'mozilla_plugin_can_network_connect' boolean.
You can read 'None' man page for more details.
Do
setsebool -P mozilla_plugin_can_network_connect 1

*****  Plugin catchall (1.69 confidence) suggests  ***************************

If you believe that plugin-container should be allowed name_connect access on the  tcp_socket by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep plugin-containe /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
