Need Help w/ Chrome CSS Drop Down Menu (v2.5)

[scootibum]

The name of the CSS style and menu is:
Chrome CSS Drop Down Menu (v2.5)
Located on this page: http://www.dynamicdrive.com/dynamicindex1/chrome/index.htm

The website I've built is http://www.paraglideonline.net

My problem lies within Firefox 3.5.2 Browser and my operating system I'm using is Macintosh OS X version 10.5.8.

All the other web browsers I've looked at view the page fine, but they only problem is Firefox 3.5.2 and this is what it looks like:

This is how its normally viewed in all other web browers:

I looked at it in FF and IE8 and don't see any difference. What specifically is the changes you are seeing?

The changes I am seeing is in the first picture that has: This is Firefox 3.5.2 on the Mac OS X 10.5.8

Everything else works just fine though but that one...It's strange.

Looks like it's a width issue where the element the menu resides in may have a conflict with the way the space is allocated. It's shoving the 2nd <li> down which is an indication there's not enough room for the whole menu.
