Description of problem:
SELinux is preventing plugin-containe from 'write' accesses on the sock_file native.

*****  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 native sock_file
Then you need to change the label on native
Do
# semanage fcontext -a -t FILE_TYPE 'native'
where FILE_TYPE is one of the following: abrt_var_run_t, alsa_home_t, antivirus_home_t, audio_home_t, auth_home_t, avahi_var_run_t, bluetooth_tmp_t, bluetooth_var_run_t, bumblebee_var_run_t, cache_home_t, chrome_sandbox_home_t, config_home_t, cupsd_var_run_t, cvs_home_t, data_home_t, dbus_home_t, devlog_t, fetchmail_home_t, gconf_home_t, git_user_content_t, gkeyringd_gnome_home_t, gnome_home_t, gpg_secret_t, gstreamer_home_t, home_bin_t, home_cert_t, httpd_user_content_t, httpd_user_htaccess_t, httpd_user_ra_content_t, httpd_user_rw_content_t, httpd_user_script_exec_t, icc_data_home_t, iceauth_home_t, irc_home_t, irc_tmp_t, irssi_home_t, kismet_home_t, krb5_home_t, local_login_home_t, lsassd_var_socket_t, mail_home_rw_t, mail_home_t, mandb_home_t, mozilla_home_t, mozilla_plugin_tmp_t, mozilla_plugin_tmpfs_t, mpd_home_t, mpd_user_data_t, mplayer_home_t, mysqld_home_t, nmbd_var_run_t, nscd_var_run_t, nslcd_var_run_t, openshift_var_lib_t, pcscd_var_run_t, polipo_cache_home_t, polipo_config_home_t, procmail_home_t, pulseaudio_home_t, pulseaudio_var_run_t, rlogind_home_t, rssh_ro_t, rssh_rw_t, sandbox_file_t, screen_home_t, setrans_var_run_t, spamc_home_t, speech-dispatcher_home_t, ssh_home_t, sssd_var_lib_t, svirt_home_t, syslogd_var_run_t, system_dbusd_var_run_t, systemd_home_t, telepathy_cache_home_t, telepathy_data_home_t, telepathy_gabble_cache_home_t, telepathy_logger_cache_home_t, telepathy_logger_data_home_t, telepathy_mission_control_cache_home_t, telepathy_mission_control_data_home_t, telepathy_mission_control_home_t, telepathy_sunshine_home_t, texlive_home_t, thumb_home_t, tvtime_home_t, uml_ro_t, uml_rw_t, user_fonts_cache_t, user_fonts_config_t, user_fonts_t, user_home_t, user_tmp_t, virt_content_t, virt_home_t, vmware_conf_t, vmware_file_t, winbind_var_run_t, wine_home_t, wireshark_home_t, xauth_home_t, xdm_home_t. 
Then execute: 
restorecon -v 'native'


*****  Plugin catchall (1.73 confidence) suggests   **************************

If you believe that plugin-containe should be allowed write access on the native sock_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
