Here's how I solved this problem:
Originally firefox profile is not loaded:
sudo /etc/init.d/apparmor restart
[OK]
* Reloading AppArmor profiles Skipping profile in / etc / apparmor.d /
disable: usr.bin.firefox
sudo / etc / init.d / apparmor status
/usr /sbin/tcpdump (enforce)
/usr/sbin/mysqld (enforce)
/usr/sbin/cupsd (enforce)
/usr/ lib/cups/backend/cups-pdf (enforce)
/usr/bin/evince-thumbnailer (enforce)
/usr/bin/evince-previewer (enforce)
/usr/bin/evince (enforce)
/usr/lib/connman/scripts/dhclient-script (enforce)
/usr/lib/NetworkManager/nm-dhcp-client.action (enforce)
/sbin/dhclient3 (enforce)
/usr/share/gdm/guest-session/Xsession (enforce)
It was found symlinks (usr.bin.firefox-3.5) which refers to a
nonexistent file:
ls-al / etc / apparmor.d / disable
lrwxrwxrwx 1 root root 31 2010-07-23 23:57 usr.bin.firefox ->
/etc/apparmor.d/usr.bin.firefox
lrwxrwxrwx 1 root root 35 2010-03-18 01:06 usr.bin.firefox-3.5 ->
/etc/apparmor.d/usr.bin.firefox-3.5
I checked the listing of files in the directory /etc/apparmor.d/
ls-al /etc/apparmor.d/

-Rw-r - r - 1 root root 708 2009-08-14 03:36 usr.sbin.tcpdump
and re-assigned symlinks usr.bin.firefox-3.5 to
/etc/apparmor.d/usr.bin.firefox, and accordingly removed symlinks
usr.bin.firefox
Restarted apparmor and saw no problems:
sudo /etc/init.d/apparmor restart
* Reloading AppArmor profiles [OK]
Profiles firefox booted without problems:
sudo /etc/init.d/ apparmor status
