Help with script in Firefox needed

[MRGTB]

I have installed a scrolling news text mod on my forum which works perfect with Internet Explorer. But not with Firefox.

The problem is the marquee itself. If I minamize the firefox browser, the marquee box does not minamize also to stay inline. It stays the full width and goes off the screen. Unlike Internet Explorer which shrinks the box bringing the width incline with the rest.

Can somebody take a look at this code and see if they know a possible fix for this for firefox, so it's cross browser compatible:

<if condition="$vboptions['news_on_off']">
<table align="center" border="0" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" class="tborder" width="100%">
	<thead>
	<tr>
		<td class="tcat" colspan="3"><a style="float:right" href="#top" onclick="return toggle_collapse('forumhome_newsbit')"><img 

id="collapseimg_forumhome_newsbit" src="$stylevar[imgdir_button]/collapse_tcat.gif" alt="" border="0" /></a>
   <strong>$vboptions[news_title]</strong></td>
   </tr>
   <tbody id="collapseobj_forumhome_newsbit" style="">
   <tr>
     <td class="alt1">
                <if condition="$vboptions['news_marquee_on_off']">
    <marquee width="100%" direction="$vboptions[news_direction]" onMouseover="this.scrollAmount=1" onMouseout="this.scrollAmount=6" loop="$vboptions[news_loop]">$vboptions[news_message]</marquee>
                <else />
    $vboptions[news_message]
                </if>
     </td>
   </tr>
 </thead>
</table>
<br />
</if>
