Jesse, Is this bug still happening? Can you still reproduce it? For your information, I loaded attachment 8688595 [details] in Firefox 47 buildID=20160606114208 and in Firefox 50.0a1 buildID=20160611041614 and did not experience Firefox application being hung or anything worth mentioning. I use Linux 3.13.0-88-generic x86_64, Qt: 4.8.6, KDE 4.13.3, Kubuntu (trusty) 14.04.4 LTS.
This was fixed by the patch in bug 1243125.
