YouTube Embeds don't display properly in Firefox or Opera

[Tim John]

Hi,

YouTube embeds are working fine in Chrome and IE (9 is all I've tested so far), but in Firefox and Opera I'm just getting the black screen.

If setting the autoplay flag, I can hear the audio, so it's working to an extent. In Opera, I can see the Playback controls appear at the top of the box when they should be sliding down to hide. This suggests the whole embed is occurring above the box's bounds.

Any idea what the problem is? This is the only decent up-to-date MooTools lightbox out there.

Interestingly, there was an update to Opera that fixed the error. So it's just Firefox left with this strange error.
