Firefox wont show "Play Tune" button in NetSuite Website

Question

Our company has an Ecommerce store created in NetSuite named Sanfrancisco Music Box. Because we sell music boxes, musical carousels and water globes, we have the tune in a "Play Tune" field where customers can hear the tune the product plays prior to making a purchase. So this is a very important element to our website.
The problem is that the "Play Tune" button shows up in IE and Chrome, but not in FireFox. It shows a long grey box where the play button should be, but no play button. I have tested this with various co-workers who have tried to view the product and play the tune in FireFox. It is the same outcome and same grey box.
Things I have tried is adding the Windows Media Player plugin and testing the play button in other browsers. The play button is in an embed tag and from all the research I've done about this, it should show the button.
You can view the same item we have been testing at the following address:

Answer 1

That is an embed tag that plays a type="audio/wav" .wav file.
You need a plugin like QuickTime that supports this content type.
It would be best though to use a file type that can be played natively by the HTML5 media player.
Then no plugin would be needed.
With this .wav file the browser console shows this error message.
