https://bugs.launchpad.net/bugs/1861408 Title: firefox apparmor messages Status in firefox package in Ubuntu: New Bug description: firefox version 72.0.1 64 bit, 72.0.1+linuxmint1+tricia , linux mint 19.3. i see there is newer ubuntu version in https://www.ubuntuupdates.org/package/ubuntu_mozilla_security/bionic/main/base/firefox , 72.0.2+build1-0ubuntu0.18.04.1 , but its changes are not for apparmor. i have not found a page for firefox bugs in linux mint sites, so i belive i should report here. but i have also asked about that in linux mint's irc and then github. i have enabled apparmor for firefox and see these types of messages in syslog: Jan 28 18:43:33 dinar-HP-Pavilion-g7-Notebook-PC dbus-daemon[735]: [system] Activating via systemd: service name='org.freedesktop.hostname1'
