Smart Tab Mute

Hello Hunters, i am pretty sure some of you might be familiar with the following situation: You are listening to music inside your browser on Soundcloud, di.fm or any other platform. As usual someone suddenly sends you a video link you wanna open. Since most of the videos have sound too, you are now looking for your music tab, pause or mute it and then start the video. When the video ends the whole procedure backwards. THAT SUCKS!!! Thats why i built this Chrome extension. It does exactly the right thing™ in this situation. When you open a new tab that needs audio, any other tab playing audio will be muted. Closing the new tab will automatically unmute the previously muted tab. Update: @noniq made this extension also available for Firefox https://addons.mozilla.org/de/fi... See the extension in action:

Good job, but it doesn't automatically switch between 2 YouTube videos playing. It will be great if the Youtube video that lost focus is muted and the currently showing is unmuted.
