SELinux is preventing /usr/lib64/xulrunner-2/plugin-container from 'write' accesses on the file /home/johannbg/.pulse-cookie.

*****  Plugin restorecon (99.5 confidence) suggests  *************************

If you want to fix the label. 
/home/johannbg/.pulse-cookie default label should be pulseaudio_home_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /home/johannbg/.pulse-cookie

*****  Plugin catchall (1.49 confidence) suggests  ***************************

If you believe that plugin-container should be allowed write access on the .pulse-cookie 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
