Great extension that does exactly what you want it to do. Rated 5 out of 5 stars

Great extension that can mute individual tabs with a simple and clear cut interface.

The maker also actively listens to user feedback.

Top notch!

Desonoriza todo el navegador, lo que efectivamente me ayudo en lo que queria hacer, sin embargo seria bueno que solo retirara el sonido de la pestaña en la que se esta ubicado.

Reapplying failed after restart Rated 1 out of 5 stars

The addon works, but only when its manually selected. After restart though, reapplying of the muting setting failed in my case, but i had it selected in the addon's setting. So this functionality is not working. The black symbol indicates sound is muted after restart, but it is not muted anymore. So one has to manually select mute every time after restart of the browser, which is a bug and should be fixed. Support is unreachable, email adress is not existent, the integrated feedback functionality doesnt work.

Last update of the addon was in 2013, so maybe that functionality is just broken whith nowadays firefox versions. My Firefox version is 43 64-bit release, muter version is 1.0.3.1-signed, we have December 2015 today.

Update: this bug was alrady reported on this page from "Bob" in February 2014:
https://addons.mozilla.org/de/firefox/addon/muter/reviews/551824/

Because this bug hasnt been fixed for a long time, i give one star for this addon for poor support.

Good add-on. Almost exactly what I needed.

But caution: if you have more than one firefox profiles, do not forget to turn muter off before you close firefox! Otherwise you'll be as unpleasantly surprised as I was the next time you open up a firefox profile: even if that profile itself does not muter installed, the tabs will be soundless anyway.

Greatly needed! Hoping for a feature to mute individual tabs.

Useful but beware Rated 3 out of 5 stars

Took me some time to realise that it was also muting my acestream player as well as firefox, mozilla firefox and flash player in Volume Mixer (Win 7). Also would be much better if you could set it to mute certain sites permanently.

Inconsistent Rated 2 out of 5 stars

It worked sometimes. But when I open FF anew with the mute icon showing MUTE, it did not work. I had to reclick it to get it to work. That's wasn't good enough to meet my needs. I'd rather just keep the speaker off entirely.

Awesome! Rated 5 out of 5 stars

Thank you so much.
In the past, if you wanted to listen to your iTunes music while playing annoyingly unmutable Flash games, you had no choice but to just deal with it. But no longer. Finally the twee repetitious tunes are silent!

The pre-1.0 versions were catch-as-catch-can, didn't always work...

BUT NOW IT IS AN ABSOLUTE MUST.

Be the absolute monarch over the babbling hordes of forgotten YouTube and Soundcloud tabs you left open. Yuan Xulei has reinvented Harry Mudd for the internet age: "Shut... UP!" with a single click. And then the pure bliss of silent obedience follows.

不错!但是有时会不起作用,时好时坏,希望开发者可以尽快修复该问题。
