YouTube Tests Improved Center-Aligned Interface

Now that many of the YouTube experiments are publicly available, it's time for something new. YouTube tests a new version of the center-aligned layout. The sidebar looks better, but it's still hidden by default. The YouTube homepage has two tabs for "What to watch" and "My subscriptions", while the header is now persistent.

Here's a video that shows a slightly different version of the experiment:

Here's how you can enable the experimental feature. If you use Chrome, Firefox, Opera, Safari or Internet Explorer 8+:

1. open youtube.com in a new tab

2. load your browser's developer console:

* Chrome or Opera 15+ - press Ctrl+Shift+J for Windows/Linux/ChromeOS or Command-Option-J for Mac

* Firefox - press Ctrl+Shift+K for Windows/Linux or Command-Option-K for Mac

* Opera 12 - press Ctrl+Shift+I for Windows/Linux or Command-Option-I for Mac, then click "Console"

* Safari - check this article

* Internet Explorer - press F12 and select the "Console" tab.

3. paste the following code which changes a YouTube cookie:

document.cookie="VISITOR_INFO1_LIVE=Gapj9bz_H8M; path=/; domain=.youtube.com";window.location.reload();

4. press Enter and close the console.

To go back to the regular interface, use the same instructions, but replace the code from step 3 with this one:

document.cookie="VISITOR_INFO1_LIVE=; path=/; domain=.youtube.com";window.location.reload();
