  Please use the same steps for Thunderbird, but replacing "firefox" with "thunderbird" instead.
  
+ == Problems launching external applications ==
+ 
+ Ubuntu ships an Apparmor profile with Firefox, but this is disabled by default. If you have problems opening files in external applications from Firefox, or problems with extensions which need to start external helpers, then please make sure that the Apparmor profile is disabled or in complain mode before reporting a bug.
+ 
+ To make sure that the profile is not in enforce mode, run `sudo aa-status`. You will see output which looks a bit like this:
+ {{{
+ apparmor module is loaded.
+ 18 profiles are loaded.
+ 18 profiles are in enforce mode.

+    /usr/bin/evince

+    /usr/sbin/cupsd (1210)
+ 0 processes are in complain mode.
+ 0 processes are unconfined but have a profile defined.
+ }}}
+ 
+ If there are entries starting with "/usr/lib/firefox" in the section "profiles are in enforce mode", then the Firefox profile has been enabled and set to enforce mode. In this case, please set it to complain mode and try again. To do this, please run `sudo aa-complain /usr/bin/firefox`. (Note, you will need to install apparmor-utils to do this)
+ 
+ If this works and the particular executable is from a software package in the Ubuntu archive, then we may consider adding an exception to the Apparmor profile. In this case, please report a bug using Apport. If the executable is from 3rd party software outside of the Ubuntu archive, then you will need to either keep the Apparmor profile disabled, or add an exception locally in /etc/apparmor.d/local/usr.bin.firefox.
