HTML/CSS drop down menu issues

[UAL225]

Hi there,

I have this drop down menu that uses HMTL and CSS3 to dropdown and show the navigation. I have a slight issue though. On IE the dropdown works like its supposed to, but on Mozzila and the such, it doesnt work. It doesnt even work on IE8. I honestly cant see why this is happining. If anyone can figure this out, or help me out here that would be great.
