Chrome: YouTube's design on the web hasn't changed much over the years, but Google seems to be looking into updating the old site. If you want to try out the new look before it goes live, here's how. As Reddit user giorgiomarinel points out, Google is currently testing a new look for YouTube based on its Material Design guidelines. We don't know when it will roll out, but you can try it now, if you're comfortable tinkering with Chrome's developer console. To do it, follow gieorgiomarinel's steps here:
1) go to https:www.youtube.com/?gl=US
2) open the developer tools (ctrl + shift + i)
3) go to the 'Resources´ tab and delete the VISITOR_INFO1_LIVE cookie for the youtube domain
4) go to the console and define the VISITOR_INFO1_LIVE cookie using the following command:
5) reload the page
You can also reuse your VISITOR_INFO1_LIVE cookie.
I tried this out myself and at first it didn't work on the YouTube page I was already logged in with. However, when I tried it incognito mode, it worked just fine. It might also not work in other browsers, but you can try it out for yourself!
In most places, the new design look much like the old site, but with a bit of polish. The most noticeable change, as you can see above, is on profile pages, which now use a much bigger header image and a cleaner tabbed interface.
