Firefox 3 and Safari doesn't load some parts of CSS

Question

I have a page that works in IE 7,8,9; Chrome and FF6 but I have some problems loading a part of style in FF3.

This is a part of the .css file:

.recipe_search_results table td ul.trait_icons {
    margin: 0;
    list-style-type: none; 
}

.recipe_search_results table td ul.trait_icons li {
    display: inline; 
    padding: 0;
}
