42 Do you have the "OpenH264 Video Codec provided by Cisco Systems" firefox add-on
43 installed (I think it comes with firefox). I have it but I still don't have
44 H.264 checked on that page and I can't play some H.264 videos like this one
45 https://www.microsoft.com/microsoft-hololens/en-us. If you have it, do you
46 mind disabling it to check if that's where you're getting H.264 support from?
47
48 I have no problems playing youtube videos without it (both HTML5 and Flash)
49 and I don't have gstreamer enabled on firefox.
