Dear Maintainer,

Testing Thunderbird 68 from experimental produces spam of denials by AppArmor:
```
type=AVC msg=audit(1563637182.506:272): apparmor="DENIED" operation="mknod" profile="thunderbird" name="/dev/shm/org.mozilla.ipc.2783.0" pid=2783 comm="thunderbird" request
ed_mask="c" denied_mask="c" fsuid=1000 ouid=1000

type=AVC msg=audit(1563637182.570:273): apparmor="DENIED" operation="mknod" profile="thunderbird" name="/dev/shm/org.mozilla.ipc.2783.1" pid=2783 comm="thunderbird" requested_mask="c" denied_mask="c" fsuid=1000 ouid=1000

type=AVC msg=audit(1563637182.622:274): apparmor="DENIED" operation="mknod" profile="thunderbird" name="/dev/shm/org.mozilla.ipc.2783.2" pid=2783 comm="thunderbird" requested_mask="c" denied_mask="c" fsuid=1000 ouid=1000
...
```
Result is black window, no UI is visible, application is completely unusable.

Adding this rule fixes the issue:
```
owner /dev/shm/org.mozilla.ipc.[0-9]*.[0-9]* rw,
```

I will work for upstream patch to fix this.
