player.setMuted(true); - Not Working in FireFox anymore?

[twitter_accounts]

Hi

Noticed Firefox browser doesn’t seem to want to mute a embed Twitch player anymore.

player.setMuted(true);

I tested the page out on Edge, Chrome, both mute correctly but firefox doesnt.

Firefox Versions 52.0.2 (linux), 53.0.0 (win10)

Anyone else experience this happening? Thanks

Here is the code I am using:

<script src= "http://player.twitch.tv/js/embed/v1.js"></script>
<div id="{PLAYER_DIV_ID}"></div>
<script>
var options = {
width: 300,
height: 200,
video: "{v140352637}"
};
var player = new Twitch.Player("{PLAYER_DIV_ID}", options);
player.setVolume(0.0);
player.setMuted(true);
player.setQuality("mobile");
</script>

The following do not work anymore on Firefox from what I have been testing.

player.setVolume(0.0);
player.setMuted(true);
player.setQuality("mobile");

But this works fine on CHROME, IE.

Can someone use the above code and try this out to see if they see the same issue with Firefox browsers?

Basically its not muting, volume controls dont work nor do quality settings. Do I happen to have a syntax issue and firefox is just not reading the javascript correctly?

Thanks
