Public bug reported:
When a firefox user has downloaded a file, the download dropdown
includes an 'Open Containing Folder' option which does what the name
implies.
When AppArmor is enabled, this button stops working. Instead, the
following denials are logged:-
dbus-daemon[6348]: apparmor="DENIED" operation="dbus_method_call"
bus="session" path="/org/freedesktop/FileManager1"
interface="org.freedesktop.FileManager1" member="ShowItems" mask="send"
name="org.freedesktop.FileManager1" pid=6874 label="firefox"
peer_pid=8779 peer_label="unconfined"
dbus-daemon[6348]: apparmor="DENIED" operation="dbus_method_call"
bus="session" path="/org/gnome/Nautilus"
interface="org.freedesktop.Application" member="Open" mask="send"
name="org.gnome.Nautilus" pid=6874 label="firefox" peer_pid=8779
peer_label="unconfined"
Adding the following permissions to /etc/apparmor.d/usr.bin.firefox
fixes the issue:-
# 'Open Containing Folder' function for downloads
dbus (send)
bus=session
path=/org/freedesktop/FileManager1
interface=org.freedesktop.FileManager1
member="ShowItems"
peer=(label=unconfined),
dbus (send)
