apparmor profile seems to be denying legitimate action

Not sure if this is something that firefox should be doing, but the following three events are in my /var/log/syslog corresponding to approximately the time I started Firefox:

Here's three more, logged when I started Firefox and navigated to twitter. These seem to occur frequently when I access a page with an embedded video(e.g. twitter, instagram, vine, etc)
