hvmenu fonts drastically enlarged in firefox

[amcgall]

1) Script Title: hvmenu

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...menu/index.htm

3) Describe problem:

The menu I created with hvmenu 5.5 look great in IE8, IE7, Opera 10.10 and chrome 4. However, when I view the page in FireFox (ver. 3.5.8) the font sizes in the menu I created with hvmenu are all drastically enlarged. This is very apparent when using font sizes larger than 9px.

I really like this script and would dearly love to use it on a site I'm developing. Does anyone have any recommendations? Any help would be greatly appreciated.
