I stumbled across marketaire.com example on how to enable the new YouTube redesign. In their walkthrough they advise that it’s only possible if your using Google Chrome or Firefox due to their developer mode function, I thought this was odd as all they were doing was adding a value to the cookie.

We’re limited to Internet Explorer at work and so I fired up the ageing IE8 and headed to youtube.com once it had loaded I manually typed the following into the address bar.

javascript:document.cookie="VISITOR_INFO1_LIVE=ST1Ti53r4fU";

I pressed enter to refresh and was presented with a plain white page and the value document.cookie=”VISITOR_INFO1_LIVE=ST1Ti53r4fU”; in the top left, I took this to mean the cookie had been updated. I reloaded youtube.com and as if by magic I was looking at the new design, the nice thing about this method is that it works on all browsers and all operating systems regardless.

Enjoy
