apparmor prevent Firefox from loading Google Voice plugin

[Simon Déziel]

Binary package hint: apparmor

I installed Google Voice plugin while I use the AppArmor profile of Firefox. To make it works I had to add this :

  # Google Voice
  /opt/google/talkplugin/*.so mr,
  /opt/google/talkplugin/lib/*.so mr,
  /opt/google/talkplugin/GoogleTalkPlugin Uxr,

I think this should be added to the profile as this plugin will probably be very popular because it allows to make free call to land lines.

Here is an extract of the log with the default AA profile (including retries as I added some authorization to the profile) :

$ grep denied_mask /var/log/kern.log

The file /etc/apparmor.d/usr.bin.firefox is provided by the firefox package and not apparmor-profiles
