May be caused by the Confluence firefox plugin.

SELinux is preventing /usr/lib64/xulrunner-1.9.2/plugin-container from 'remove_name' accesses on the directory settings.sxx.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that plugin-container should be allowed remove_name access on the settings.sxx directory 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
