Bug Description

When I launch Firefox with apparmor enabled, I sometimes get the following error:

Mar 6 17:43:43 tigreraye kernel: [14527.976158] audit: type=1400 audit(1457282623.012:97): apparmor="DENIED" operation="open" profile="/usr/lib/firefox/firefox{,*[^s][^h]}" name="/sys/devices/system/node/node0/meminfo" pid=12864 comm="firefox" requested_mask="r" denied_mask="r" fsuid=1000 ouid=0

Adding the following lines to the apparmor profile fixes the issue:

/sys/devices/system/node/node0/meminfo r,

The Firefox AppArmor profile shipped in Ubuntu 18.04/bionic includes this rule, so this should no longer be an issue.
