Sometimes, while we are browsing on the internet, we like to listen to music or watch a movie but, occasionally, some websites might play videos, sounds and advertisement automatically, and this is one of the most annoying things that can happen, especially if you’re in a public (silent) place. So is there a way to mute it all?
Finally I’ve found a very interesting Firefox Add-on that lets you mute every sound that comes from your Firefox’s windows.
It’s name is “Muter“: once installed, it gives you a sound icon in the Firefox addon-bar at the bottom. Just click on it and all sounds from your browser will be completely muted.
The default keyboard shortcut for muter in Firefox is Ctrl+Alt+M, but you can also change the keyboard shortcut, the icon style for the mute button or even select from around 7 themes as well.
If you are using Windows 7, it has already such a option to mute sounds from firefox or any program.

I know, but sometimes is good to have more than one way to do something!
