I have Embedded three Youtube videos, they work perfectly in ALL BROWSERS except Firefox.

Tried clearing cache on server side, cleared cookies & cache locally, tried 18 different computers, tried Windows 7, Windows 8, Linux Ubuntu 12.10, Fedora 16, Mac OSX, iOS, Android 4.0.3. Tried Firefox versions 7 through 15.

Even tried redoing website from scratch.
Same problem all around... Videos do not load in Firefox and Firefox only.

What am I doing wrong?

I have looked all over, asked around on IRC, posted questions in forums but no luck.

I have even tried the old youtube embed codes. Vimeo embed iframes work perfectly fine!

My code is as follows: http://pastebin.com/T3w09bqW
--Note: the middle video is using the old youtube embed code.--

Here is a picture.
