Firefox crashes using WebRTC
Every time a website initializes WebRTC capabilities, it inevitably leads to a complete firefox crash. I have tried using different websites (roll20.net as well as appr.tc) and the problem is the same. I have also tried all of the steps mentionned in this article: https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems and the best I have achieved is now containing the crash to a tab crash, not a firefox crash. I am running Firefox 54.0.1 (x64) on Windows 10 the webcam used is a Logitech C920.

The crash report is several pages of data. We need the report numbers to see the whole report.

Hmm oddly enough there are no crash reports generated by those crash. However, and I tried it once again to be sure, I get redirected to the page saying "oops this tab has crashed" (or something along those lines since my browser locale is french)

Please let us know if this solved your issue or if need further assistance.
Interesting read however I cannot disable WebRTC as I need it for voice & video chat within Roll 20. After turning off this setting I confirm though that the crashes are gone, however I cannot receive or send voice/video streams.
