I don't think you need to update it particularly, it might just be which browser you're using, I know some browsers don't work with it for some reason I'm still trying to debug, I tested it with Chrome and it worked fine. But if you can't play it in browser, if you're on a Windows device there's also a Win32 executable download for standalone.
