The built-in Internet Explorer supports for modern web standards on Xbox One. However, when I booted up IE Browser to watch some online TV shows or full episodes from website, most of them are not working and only show a few error message “Internet Explorer in Xbox 360 cannot install Flash”. It seems to be no available flash player for being downloaded onto the new console. How can I stream video via this app? Is it complained about Flash?
The Internet Explorer on Xbox One is crippled, because it is not fairly full-featured version and doesn’t support Flash which is a dead media for the most part, even Adobe encourage people to use HTML5. So HTML5 is the future with the standard for web videos and the IE app does do the good job with HTML 5 video playback.
For YouTube, access www.youtube.com/html5 with enable HTML5 support and it works fine in IE. But a lot of streaming sites using Flash won’t be accessible on the XB1, such as anime sites, Plex, Pandora, South Park Studios, and music players.
