Disable default alert sound for Firefox web notifications

Question

I'm using the Web Notification API to show desktop notifications from my web app under OSX.

In Firefox only, when a notification is triggered, it also plays a sound (in Safari and Chrome, using the exact same code, only the notification displays and there's no accompanying sound effect).

I'd like to disable the notification sound in Firefox, but I can't find anything in the documentation about controlling it. Is this possible?

Answer 1

On OS X, go to System Preferences, then Notifications. Choose Firefox and uncheck Play sound for notifications to get rid of the sound.

Answer 2

The Web Notification API now has the config option silent, but support is patchy, Chrome v43+, Firefox (not yet supported).

I'd suggest building silent into your notifications then if/when Firefox support it, it will just work.
