Hey guys,

I think the latest update broke the video playback, at least on my side. The video (html,webm....) is loading, but the playback simply does not start. Starting firefox without firejail works without problems, so I guess the problems has to be somewhere in firejail, maybe in my config?

Firefox: 44.0
firejail: latest version from git.

Video playback works just fine for me with this as my profile file.

include /etc/firejail/firefox.profile
whitelist /home/chiraag/.mozilla
whitelist /home/chiraag/Downloads/
whitelist /home/chiraag/.pulse/
whitelist /home/chiraag/.config/pulse/
whitelist /home/chiraag/.config/gtk-3.0/
whitelist /home/chiraag/.config/google-googletalkplugin/
whitelist /home/chiraag/.gtkrc-2.0
whitelist /home/chiraag/.gtkrc.mine
whitelist /home/chiraag/.Xauthority
private-etc hosts,passwd,mime.types,fonts/,mailcap,iceweasel/,xdg/,gtk-3.0/,resolv.conf,X11/,pulse/,asound.conf,adobe/,gcrypt/,alternatives/
shell none
seccomp

where /etc/firejail/firefox.profile is the default that is shipped.

The two main areas I see a difference are with your whitelist (I don't include whitelist-common) and that you enable an additional protocol (netlink). Neither of these should be affecting your video playback, however. Ah...maybe the problem is that you're not whitelisting ~/.pulse? If you're using PulseAudio, you have to do that (I've had issues with video playback if the audio subsystem isn't working).

Try version 0.9.40, there have been lots of fixes. If you still see the problem, I'll reopen the bug.
