Youtube & CSS Help…

I am coding my first worpress theme (I’m really more piecing it together from other themes and throwing in some of my own magic ;). Anyway. I had a youtube video inserted in the sidebar and working. I continued editing and fixing little issues (lots of little issues). I hadn’t really paid attention, but somewhere during the process, my youtube video stopped working in firefox only. It is working fine in IE7. It’s really weird. I have exhausted my limited resources and knowledge and can’t figure out at what point I lost the ability to see the video in firefox. So, here is the css and link to the blog. If anyone can help, it would be SO appreciated!!!

PS – I’m sure my code is pretty ugly, sorry. Also, I have searched for solutions and can’t find any similar to this…
