very new html features problem... (youtube live chat)

[Leamucho]

Hello, the problem appears as I try to use GET from the popout chat of a live YouTube video:

Reponse Content: <style nonce="+glrZXZT5SrXVG9iZMLTqA">html,body,#page,#content-container{width:100%;height:100%;margin:0;padding:0}body{background-color:#fff;color:hsl(0,0%,6.7%);font-family:Roboto,Arial,sans-serif}a{color:hsl(0,0%,20%);font-size:20px}#content-container{position:relative}#content{position:absolute;top:50%;left:0;right:0;transform:translate(0,-50%);text-align:center}h1{font-size:48px}</style><style name="www-roboto" nonce="+glrZXZT5SrXVG9iZMLTqA">@font-face{font-family:'Roboto';font-style:normal;font-weight:400;src:url(//fonts.gstatic.com/s/roboto/v18/KFOmCnqEu92Fr1Mu4mxP.ttf)format('truetype');}</style><script name="www-roboto" nonce="WU6AsU0EzQdRs5G2xVigiw">if (document.fonts && document.fonts.load) {document.fonts.load("400 10pt Roboto", "P"); document.fonts.load("500 10pt Roboto", "P");}</script>

Ah, não!

Parece que a versão do seu navegador é antiga. Atualize para usar o chat ao vivo.

Reponse Content-Length Header:

The last part the important one, although in Portuguese, sorry, Brazilian server.... it says something like "your browser version seems old, please update to use the live chat"
I imagine you guess I'm trying to pick up the live comments... soon help would be really, really appreciated!
