I had this in my logs:
Jan 21 16:32:30 localhost kernel: [24900.927939] audit: type=1400 audit(1421879550.441:534): apparmor="DENIED" operation="bind" profile="/usr/lib/firefox/firefox{,*[^s][^h]}" pid=12356 comm="plugin-containe" family="unix" sock_type="dgram" protocol=0 requested_mask="bind" denied_mask="bind" addr="@676F6F676C652D6E61636C2D6F316431323335362D3339310000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000"

$ aa-decode 676F6F676C652D6E61636C2D6F316431323335362D3339310000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

$ aa-decode 676F6F676C652D6E61636C2D6
Decoded: google-nacl-`

So I tried the following:
unix bind type=dgram addr=@google-nacl*,
unix bind type=dgram addr="@google-nacl*",
unix bind type=dgram addr=@676F6F676C652D6E61636C2D6*,
unix bind type=dgram addr="@676F6F676C652D6E61636C2D6*",

but none of them match. The best I could do was:
unix bind type=dgram,

This is likely going to be important for snappy since snappy will have the concept of different coordinating snaps interacting via abstract sockets. What is interesting is that this seems to work ok for some things, eg:
./lightdm: unix (bind, listen) type=stream addr="@/com/ubuntu/upstart-session/**",
./lightdm: unix (bind, listen) type=stream addr="@/tmp/dbus-*",
./lightdm: unix (bind, listen) type=stream addr="@/tmp/.ICE-unix/[0-9]*",
./lightdm: unix (bind, listen) type=stream addr="@/dbus-vfs-daemon/*",
./lightdm: unix (bind, listen) type=stream addr="@guest*",

Is this something in how firefox is setting up the socket?
