Hello, I bought a course some time ago in Zenva web page, I tried to access to videos and I can't access it in firefox, but I can in another browser. It only happens to me on that site, on Vimeo I can see them (I don't know if it's because what I'm trying to see is hosted on Microsoft Azure media services). I solve it by disabling the Facebook container plug-in for that page. My login to that page is with username and password, not with Facebook. Regarding Facebook, the only thing I see on that page is a link to zenva's Facebook page. Is there any way to watch them in my usual browser (Firefox) and not have to install another one or disabling Facebook Container to that page? In the attached file I have put the errors that it shows me. Thank you!
