side bar boxes breaking in firefox??

[ddgdaily]

I have been working mostly in IE7, but have been using the firebug tools etc.. in firefox to make some changes, and I have noticed that the sidebar boxes aren't displaying correctly. The theme demo page however looks fine.

I haven't actually made any changes to the sidebar.php other than to delete the code for some of the default widgets, but I am wondering if I accidently broke something else??? It displays perfectly in IE. help please.

sidebar php is -

<div id="sidebar">
    	
	<ul id="sidebarwidgeted">
        
        <?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar('Sidebar Top') ) : ?>
        
   		  
        
            <li id="quick-search" class="widget">
                <h2>Quick Search</h2>    
                <?php wp_dropdown_categories('show_option_none=Select category&hierarchical=true'); ?>
                <script type="text/javascript"><!--
                    var dropdown = document.getElementById("cat");
                    function onCatChange() {
                        if ( dropdown.options[dropdown.selectedIndex].value > 0 ) {
                            location.href = "<?php echo get_option('home');
                ?>/?cat="+dropdown.options[dropdown.selectedIndex].value;
                        }
                    }
                    dropdown.onchange = onCatChange;
                --></script>
