Media resource data:audio/wav;base64,UklGRiQAAABXQVZFZm10IBAAAAABAAEARKwAAIhYAQACABAAZGF0YQAAAAA= could not be decoded.

uncaught exception: undefined

That doesn't appear to be a valid audio file. You'll get a load error with that in any browser, not just Firefox.

That is the error, not the file. The file plays, that's the error in the console, even though the file plays.

[goldfire]

Can you provide a reproducible test case (possibly a jsfiddle or at least access to the file throwing this error)?

Just hit "unload()" on any Howl object on Firefox. The loaded file is not relevant. What you said above that doesn't look like a valid audio file is actually from Howler's source code, inside the unload method.
