Couldn't get this to work in Chrome on OS X, suspect it has something todo with some of my extension(s) blocking needed stuff.<p>In addition to an "Incognito Mode" (where you might still want some extensions enabled) we really need a "No Extensions/No-(Popup)-Blocking mode" so sometimes one can enjoy stuff like this while keeping sane during normal day to day browsing.<p>EDIT: just watched after disabling all my extensions and restarting (yes, that was necessary) Chrome, only to realize that i'd already seen it in 2011...
