Does exactly what it says on the tin :)
Very useful, I use it since quite a while and don't have any slightest complaint.

I love that it needs no permissions. As it should be.

Simple and does exactly what's needed. Should be built in to Firefox.

Thank you for this addon, not sure why this is not in Firefox at all. Super helpful!

Actually made a Firefox/Mozilla account SOLELY to give this plugin the 5 star rating it deserves. Can't even count how many times Windows will blue screen while I have a hundred tabs open across multiple windows and booting back into windows and restoring the session getting bombarded with all the tabs with YouTube videos all autoplaying while trying to hunt them down; now its just a click of a button on my hotbar.

5/5 Would absolutely recommend if you're also a tab master.

THANK YOU.
Youtube will randomly start playing shorts in dormant windows. And I average over 150 tabs... so its a needle in a tabstack.
This add-on works!

Nice. Does what it should do. But would be more useful tho if you could see a list of playing tabs if multiple ones are playing.

Lol

Simple and works perfectly as of Firefox 112

Perfect and simple -thanks

Very good, necessary extension. It has shortcut setup chapter, also!

Works! Thanks. Just recommended it: https://superuser.com/questions/1662429/how-to-find-which-firefox-tab-is-playing-audio-without-installing-extensions#comment2758751_1662434

Does what it says on the box! This extension provides an easy way to find that pesky tab playing in the background. I wish this functionality was built into Firefox.

This is an absolute must-have for me, my firefox, my adhd and 200+ open tabs.

Only used it once so far - but IT SAVED MY SANITY. Was able to instantly locate the one tab (among about 900 open tabs!) that was playing audio intermittently in background. (For some reason, could not see it in Tree Style Tab, another highly recommended add-on.)
