Moving to apparmor because this will be handled in a new abstraction: /etc/apparmor.d/abstractions/ubuntu-browsers.d/webapps.

I can reproduce the first denial, but not the second. What website did you visit that triggered this?

I got it before visiting a website. After bisecting through my plugins,
it appears to be lastpass which is trying to create the /run/shm/

(It still works fine even though the mknod call is blocked, FWIW.)
