Hi jc-moz, I initially thought so, but switched AppArmor to complain mode (rather than enforce) and got the same results (also the Mozilla-built Chromium works fine). Current AppArmor status:
$ sudo apparmor_status [...] 17 processes have profiles defined. 9 processes are in enforce mode. /sbin/dhclient (2869) /usr/sbin/cups-browsed (7130) /usr/sbin/cupsd (7125) /usr/sbin/dnsmasq (3073) /usr/sbin/dnsmasq (3074) /usr/sbin/dnsmasq (3089) /usr/sbin/dnsmasq (3393) /usr/sbin/libvirtd (2495) /usr/sbin/ntpd (4833) 8 processes are in complain mode. /usr/lib/firefox/firefox{,*[^s][^h]} (7492) /usr/lib/firefox/firefox{,*[^s][^h]} (7544) /usr/lib/firefox/firefox{,*[^s][^h]} (7702) /usr/lib/firefox/firefox{,*[^s][^h]} (19925) /usr/lib/firefox/firefox{,*[^s][^h]} (19963) /usr/sbin/avahi-daemon (2145) /usr/sbin/avahi-daemon (2199) /usr/sbin/nmbd (3616) There may be something else than AppArmor going on, but I don't know what.
