Description of problem:
SELinux is preventing /usr/lib64/firefox/plugin-container from 'read' accesses on the file .

*****  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 -P unconfined_mozilla_plugin_transition 0

*****  Plugin catchall (1.81 confidence) suggests   **************************

If you believe that plugin-container should be allowed read access on the  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 plugin-containe /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
