Chrome: If you tend to bounce between a lot of different videos or sounds online, you know how much a pain it can be to have sound coming from multiple tabs. Smart Tab Mute ensures only one tab can play sound at a time. If you’re playing audio in one tab, then start in another, Smart Tab Mute automatically mutes the first one until the second is done playing. When it’s finished, it will start playing the last thing you had playing. If you listen to music in your browser, this is a great way to cut out the step of pausing it when you want to watch a video.
