recently rising and on #7 on the score-board for 45.0b10 currently. many comments link this crash to starting a facebook video call & some other sites accessing the webcam (coursera, chatous.com). the signature seems to have taken off after february 10th across channels (maybe facebook switched to webrtc then):

Probably a dupe of bug 1247741, which landed on central on Feb 21, and Aurora, which landed on Feb 25.
