Got Netflix working again with Firefox 50. I had to adjust the User Agent (using "User-Agent Switcher" plug-in) to: Linux / Chrome 53: Mozilla/5.0 (X11; Ubuntu; Linux x86_64) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/53.0.2785.34 Safari/537.36
And I do not need the "export MOZ_DISABLE_GMP_SANDBOX=1" workaround anymore, which helped to avoid a crash with 49.0.2. when widevine was started (after Ubuntu 16.10 upgrade). I guess this issue was related to problem described here. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1638719 Title: Widevine crashes on Firefox 49.0.2 and Ubuntu 16.10 Status in firefox package in Ubuntu: Confirmed Bug description: After upgrading to Ubuntu 16.10 the Widevine plugin of Firefox crashes when trying to watch a video, while Widevine works fine in Chrome. Before upgrading it worked without problems with the same Firefox version. So I assume there is some conflict with Ubuntu. This happens on all my three devices. I logged into guest mode and tried it there, but same problem occurs.
