I'm using chrome and Beta will not load. I just get a black screen.
I am having the exact same problem. Blackscreen when using Edge, works great when using Chrome.i do nothing with chrome, only when I have problem with IE to look and this morning i tried to logging and that worked and logged out. Nothing about HTML 5 at that moment.
Yes, I can confirm this. Vivaldi identifies as Chrome. Yet it doesn't work with html5.EDIT2: weird: I am using vivaldi as main browser, the "detectmybrowser"-site identifies it as chrome, yet your system does not allow html5 (vivaldi is based on chrome)
