Nice addon. I was looking for this for a long long time. Great job.
Often, a lot of tabs play loud noise when I open them up.
Now, I won't ever need to worry.

Perfect!!

There seems to have been a surge these days, in my country at least, of websites, even professional ones relating to stuff like financial services, etc., to have a "May I help you?" kinda helper bots pop up with an audible ding every time you access their webpages. It gets very tedious after a while.

This add-on is exactly what I needed! Well done, developer! Having a whitelist means I can easily and permanently unmute websites like youtube, etc.

My one nitpick is that there should be an option to hide the muted audio icon on each and every tab that is open. Someone like me who has tens of tabs open at a given time, it can look very crowded. I hope the developer take this into consideration for a future update. Else, perfect!

EDIT: I noticed that Developer has replied to another review regarding the audio icon, and suggested editing the userchrome.css to achieve the same. While this worked for me in regular tabs, it did not remove the icons from pinned tabs. Maybe developer can help me in this regard.

Super Useful

I never knew I needed this in my life. I have to do virtual labs for school and they always open in a new tab. They make loud clicking sounds any time I move something around in the virtual lab. By muting every site by default and remembering sites that have been un-muted like YouTube. Simple but great.

This brilliant extension would be greatly improved by an option to permit automatic un-muting of the focused tab.

Still great!

Works perfectly......love it.....has helped so much.

innovative whitelist feature; THANKS!
maybe the reverse could be a thing too (all unmuted except blacklist) -- it would look like this:
white list = always UNmuted.
blacklist = always muted.
everything else(default action): we select option as either muted or unmuted.
this would give us maximum flexibility.

Great! Originally thought that the speaker icon was enabled by this plugin: "I am only missing an option to remove the speaker icon as it gets hard to hit that in pinned or small tabs!"

The speaker icon is enabled by Firefox and is independent of this plugin. You can disable it via "browser.tabs.showAudioPlayingIcon" in the Firefox settings!

Also thanks to abba23 for responding in a helpful manner :)

It's a minor thing if your are going down the highway, and as you get a near a town you start seeing billboards.

But what if instead, your nice tunes on the stereo got interrupted with blaring advertisements?

It's a damn shame, but that's what the internet has become with all of the advertisement spending.

Thanks, very much, for developing and posting this add-on. It should be a Firefox default.

Perfect! Thank you!!!!

It is frustrating and embarrassing when Bloomberg blasts audio in a quiet shared office setting. This add-on mutes all sites by default until they're added to the whitelist. Clicking on the unmute icon on the tab adds the site to a whitelist. Some sites like YouTube are expected to always play audio and adding those sites to the whitelist makes a lot of sense. While stopping video from playing is nice to have, muting audio from playing is a MUST HAVE productivity tool. Love it! Highly recommend.

This message is not a paid advertisement. It is my personal endorsement towards how helpful this add-on is to me.

Essential addon, could we block domains without needing www. infront? Would love to block autoplay vids too

Nice and simple. Does the job.

De todos los que he probado, es el que mas se ajusta a mis necesidades.

This should be a default feature on Firefox

Endlich eine Möglichkeit unerwünschte Sounds stumm zu schalten.
Eine einfache, aber geniale Idee!

I HATE (!) pages that play unasked sound. Thank you for this important addon.
