Chrome Helps Silence Noisy Sites
In the latest beta version of Chrome, Google has made a useful tweak to help users identify noisy tabs. You’ll now find a speaker icon next to the name of any tab playing audio, so you can easily find the disturber of the peace. Further, you’ll also see corresponding icons on tabs using your webcam, or tabs you’re casting to a Google Chromecast.–The Verge 11/11/2013
