Bug Description

In order to use sites that make use of WebRTC's webcam support, firefox needs access to the /dev/videoN device. When I applied the latest firefox update over the last week, apparmor was set to enforcing mode, which broke sites that use WebRTC, like https://talky.io.

$ lsb_release -rd
Description: Ubuntu 16.10
Release: 16.10
$ apt-cache policy firefox
