Firefox doesn't support this audio format.

Web Console:

Cannot play media. No decoders for requested formats: audio/x-wav

Firefox doesn't play the most basic, common, and ancient audio file format.

Some browser.

There are no licensing fees for WAV. It's unencumbered. Why would Mozilla not include this??

This seems to be only a problem with the width of the player bar. I can play the WAV file via the right-click context menu.

You can use a JavaScript bookmarklet or run the code in the Web Console to set a usable width for this element.

• javascript:void(document.getElementsByTagName("audio")[0].style.width="300px");

I see, so ff DOES support wav.

it's just like I said. ff is mangling the UI.

Thanks for workaround, but this is a bug right?

It is not really a bug, but about the CSS code the website uses for this element that isn't working properly in Firefox as it sets no width explicitly.

if no width is specified, then obviously Firefox should render in such a way that the entire control is visible. Same as the other browsers. This is just ... garbage.
