Hi,
Thanks for the report. Can you retrieve this crash report on your about:crashes page in Firefox? Does this only happen for a specific video? or this happens on every video?

Hi

I was able to reproduce it with several websites, however it does appear to be inconsistent and some times the videos can play on YouTube. Even videos that have previously not played can sometimes play. I am able to reproduce it on several websites:

YouTube.com
cnn.com (main site does not load at all)
bbc.co.uk

Also please see the thread from Tor Browser discussion which appears to be similar/related issue:

I have posted the crash ids below I hope this is what you need?

I'm going to dupe this into bug 1683579 they appear to reference the same issue and 1683579 currently has richer information on the crash stack. We'll continue to investigate in bug 1683579.
