It sems to have to do with some firefox plugin or perhaps add-on.
So, not sure how to answer your question because all I can see in the
"details" is:
SELinux is preventing plugin-containe from write access on the directory
#SharedObjects.
***** Plugin mozplugger (93.0 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_labels (6.67 confidence) suggests *******************
If you want to allow plugin-containe to have write access on the
#SharedObjects directory
Then you need to change the label on #SharedObjects
Do
# semanage fcontext -a -t FILE_TYPE '#SharedObjects'
where FILE_TYPE is one of the following: admin_home_t, cache_home_t,
config_home_t, data_home_t, dbus_home_t, gconf_home_t,
gkeyringd_gnome_home_t, gnome_home_t, gstreamer_home_t, home_cert_t,
icc_data_home_t, mozilla_home_t, mozilla_plugin_rw_t,
mozilla_plugin_tmp_t, mozilla_plugin_tmpfs_t, mplayer_home_t,
pulseaudio_home_t, texlive_home_t, tmp_t, tmpfs_t, user_fonts_cache_t,
user_home_dir_t, user_home_t, user_tmp_t.
Then execute:
restorecon -v '#SharedObjects'
***** Plugin catchall (1.73 confidence) suggests **************************
If you believe that plugin-containe should be allowed write access on
the #SharedObjects 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
