This issue can be mitigated by adding the following lines to FF's
apparmor profile:
dbus (send)
bus=session
interface=org.gtk.vfs.Daemon,
dbus (send)
bus=session
interface=org.gtk.vfs.Mount,
I've uploaded a patch named VERSION 5 at
https://bugs.launchpad.net/bugs/1659988 which contains these lines.
