Description of problem:
I was trying to log in to my internet bank which generates a random key on every login.
SELinux is preventing /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.19.x86_64/jre/bin/java from 'append' accesses on the chr_file random.

*****  Plugin mozplugger (99.1 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 (1.81 confidence) suggests  ***************************

If you believe that java should be allowed append access on the random chr_file 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 java /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
