Comment 2 for bug 712584

I was getting alerts, via apparmor-notify, almost identical to the ones described here, although I am using Firefox 3.6.13, when I visited various websites, although I didn't notice any missing graphics. That may be because the graphics were web ads, which I am blocking via Adblocker Plus. This is a recent change -- I only started getting such alerts a few weeks ago.

I added to /etc/apparmor.d/local/usr.bin.firefox the following:
/dev/nvidactl rw,
/dev/nvidia0 rw,
/proc/interrupts r,

and that seems to have stopped the alerts. As in the original description, I started with the first two, and only then got the /proc/interrupts error, so I added it as well.
