As advertising is becoming more and more prevalent and is being allowed to automatically start running on a page we need a way to either prevent that or at the very least turn an option to off any sound that is coming from each individual page/tab that we have up but is not the currently viewed page. A group option would not work because of things like Pandora so it would have to be on a tab by tab basis or like popups on a browser basis with exceptions (although that could lead to a lot of exceptions). It seems that I am watching something and on another tab an advertisement will auto start and drown out what I was watching. Then I have to go and locate the page - sometimes difficult if you have a bunch of tabs open at one time like I normally do - and turn off the ad or mute the ad... something along those lines. So figure out how to kill the ads.
