It seems Google has decided to overhaul the User Interface of it’s entire services. Few months back we’ve seen the redesign of Google’s homepage, then few weeks back we’ve seen complete redesign of Gmail, and now it seems that YouTube‘s next.

But for YouTube, it’s not that easy. Right now, Google’s is just testing the new layout and it’s not yet available even in TestTube. But fret not, the method to enable new UI is pretty straight-forward and easily revertible too. All you need is to play with the cookies, and in case you want to revert to older looks, just delete the cookie, simple!

So, how do you get the new UI? Just follow these easy steps –

• Open your web browser and navigate to YouTube. Right now, this method seems to work only in Chrome, Firefox and Internet Explorer 9 (I’m using the Chrome for the process right now).
• Open developer tools – Press F12 in IE9, Ctrl+shift+j in Chrome and Ctrl+shift+k in Firefox for quickly open the developer tools.
• Now navigate to console part and enter the following code:

document.cookie=”VISITOR_INFO1_LIVE=ST1Ti53r4fU”;

Just input the code shown and you’re done.

• Done! Just close the developer tools and refresh the YouTube page and you’ll land into new refreshed page.

After the refresh, you’ll see a simple guide to the changes done. If you like follow these to learn or simply take a look at the images below. Also to note, these changes goes pretty well with CosmicPanda, released by YouTube some time back and I strongly recommend to use this as well to have an immersive experience.
