- The single biggest problem I have going from Chrome to Firefox is losing the button for "take me directly to the tab that is currently playing audio". I think I found an addon for this once but I don't think I got it working, now I can't find it again.

What do you *recommend* for this? In the most ideal world I could either quickly get currently playing audio OR get a short list of tabs that *recently* played sounds ("what just beeped?").
