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.

/etc/apparmor.d/abstractions/ubuntu-browsers.d/multimedia in Ubuntu 18.04/bionic contains the fix.

Marking the Firefox bug as Invalid, since the issue was fixed by updating the AppArmor abstraction. (I.e. no change to the firefox package was/is needed.)

Changed in firefox (Ubuntu):
status: New → Invalid
