Edge Animate not playing in Chrome or Firefox?

Hi guy's,

I've embeded an Edge Animate file as an i-Frame so the animation can be viewed in our companies LMS (as it uses a WIZIWIG editor to create the content), the animation plays in Safari and on iPad etc, but it wont play on Chrome or Firefeox?

Does anyone have any idea on how I can make sure it plays on all browsers please?

I'm a bit of a newbie, so sorry if this is a stupid question?

Cheers,

Stu
