CentOS - Nov 2017 - Firefox print to file fail silent & side notes of cms4all.

Hello everyone,

in time when i start to rebuilt my csm4all-media, I tryed to print into
file from firefox. The print box close but no pdf is created. With
cups-pdf works, but:

- You can not name the printout
- can not change the directory from userland, only with cups
configuration.

Where is the hunt? I only wanne tell, that is not my domain.

Side note:

cms4all-kernel, cms4-all-drivers, cms4all-mesa is in takt, but I will
push information when cms4all-gstreamer an cms4all-media closed in my
private Project. My aspect "best of" isn't closed yet, still
experimental. Will take addional weeks, as i did it 2016 for centos.

@Nux, my VLC is still more stable as yours and I don't no why.

Yes I'm still there, but private and work takes to much time. I'm still
there ...

Sincrely

Andy

While attempting to print to PDF today I ran into this same issue. It's 
SELinux throwing the error, and here is what setroubleshoot suggests:
"SELinux is preventing java from write access on the file 
/home/lowen/Documents/personal/printed-copy.pdf.

*****? 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
"

I made a physical print for now, as I'm going to investigate a bit 
before I blindly enable a boolean like that.

There are several mozilla-related SELinux booleans:
[lowen at dhcp-pool101 ~]$ getsebool -a|grep mozilla
mozilla_plugin_bind_unreserved_ports --> off
mozilla_plugin_can_network_connect --> off
mozilla_plugin_use_bluejeans --> off
mozilla_plugin_use_gps --> off
mozilla_plugin_use_spice --> off
mozilla_read_content --> off
unconfined_mozilla_plugin_transition --> on
[lowen at dhcp-pool101 ~]$
