Noise Add sound events to Firefox
Noise Firefox Add-on
The Noise Firefox add-on can play sounds for more than 20 browser events such as when opening a new tab or when a popup has been blocked. You have the option to specify a different sound of your choosing for each action and you can also create your own sound events.
Setting Up Noise
Noise installs with just a few of its sound events enabled and it uses the same sound for each event. To begin customizing Noise, follow the path below to get to its preferences window.
Press Ctrl (or Cmd) + Shift A (opens the Add-ons Manager) > Noise > Options
Setting up Noise is a very simple point and click operation. You can either customize Noise by right clicking on a sound event or by using the buttons provided at the bottom of the Noise preferences manager. The following are instructions for using the right click option.
Begin by selecting an event that you would like to enable and/or customize.
When you right click on your chosen sound event you will see a menu providing several options. For now we will be editing your selection to change the sound for it.
In the Noise Edit window, click on the Choose button located on the "Sound file:" line.
A window will open up allowing you to navigate to the folder that contains your sound files.
That folder can be any folder that contains .wav files. For purposes of this demonstration I'm using the Windows sounds folder that you can access by going to C (or your primary location that contains Windows files) > Windows > Media.
Select the sound file that you would like to use and click on Open > Ok > Enable > Ok. Repeat the steps for each sound event. It's far less work than it appears.
