[Player] Howler.js not playing stream in Firefox

[majick777]

Forked from issue #472

Reported by @RadHausStudio
"The embedded player on the site won't play in Firefox. I tried on both Linux and Mac."

@majick777 tested:
I tested both jPlayer and Amplitude in Firefox (on Windows) and both worked for me (though Howler still does not.)

Additional information:
Mozilla: The MP3 audio format is supported in by Firefox/Firefox for Android/Firefox OS when the operating system provides an MP3 decoder. So I'm guessing that the operating system you're testing this on does not provide an MP3 decoder.
Also, you may have a fallback audio stream in OGG format rather than MP3 and it is recommended for full browser coverage to have both if possible.

I've tested setting the html5 flag in the Howler initialization to false as suggested by the above issue thread (preload is already set to false.) Unfortunately, it hasn't made any difference in my testing yet.

@majick777 I just tried to check this again and it's still now playing for me in Chrome using Amplitude, nor it is playing on mobile. Not sure if it's the stream but the meta data is coming through, so I can't imagine it would have changed.

Howler has been disabled in 2.5.7 since the issue still hasn't been fixed.

@tonyzeoli I believe the issue with Amplitude and Chrome on the demo site was because of an old streaming URL. Having updated that, it seems to be working fine again.
