link_to_remote not working in FF 2.0

Hi,

I build in a textarea where I can write markdown code according to
this article http://www.railsdiary.com/diary/ajax_markdown_preview.

It works fine in Safari but for some reason it doesn't work in
Firefox...

This is my code:

View

I think I found the problem! I also used the Rico framework to round
corners and when I removed the rico reference the preview link worked
just fine....
