I just checked using Firefox and I can’t see it either.
I looked at your source code and found this:
<p><object width="480" height="385"><param name="movie" value="https://www.youtube.com/v/DCtrmbuSKpQ?fs=1&hl=en_US"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" </p>
The <param name="allowscriptaccess"
doesn’t have a closing tag and that is probably the reason it isn’t showing. Also, you don’t have a closing object tag.
Also, if you send your site through the W3C validator, it picks up the same issue: HERE.
Check your video embed code in your post and see if you can find the problem there. I would suggest turning off the visual editor if you use it; sometimes you can get weird coding problems when using it. ??
… What I am curious about is why Safari would show the video.
EDIT: I just viewed your site in Safari. Even though the same problems exist (checked the source code again), Safari loads the video. Fix the embed and object problem and the video should show on the ‘fox.
