How do I play a sound when a popup window opens.
I don't want to block the popup. It's just a notice of a timeout for a site I frequent. I want to enable a sound to play when the popup appears so I know the site is about to time out. I'm using Firefox 35.0.1 on a MacBook. Thanks in advance for any help!

You may need an add on or third party software for this.
