Problem w/ Mozilla and Logo

[Chimpie]

For some reason in Mozilla Firefox my logo is being thrown to the right. (It's fine in IE7.)

Here's the code:

<!-- logo -->
<a name="top"></a>
<table border="0" width="$stylevar[outertablewidth]" cellpadding="0" cellspacing="0" align="center">
<tr>
<td style="background-image:url('$stylevar[imgdir_misc]/leftborder.gif'); background-repeat:repeat-y;" height="100%"><img src="$stylevar[imgdir_misc]/leftborder.gif" border="0" alt="" /></td>
<td valign="top" width="$stylvar[outertablewidth]" class="page">

<br />
<table border="0" width="$stylevar[outertablewidth]" cellpadding="0" cellspacing="0" align="center">
<tr>

<td align="right" width="360">
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;
<a href="$vboptions[forumurl]"><img src="$stylevar[imgdir_misc]/logo.gif" border="0" alt="" /></a></td>

</tr>
</table>

<!-- /logo -->

<!-- content table -->
$spacer_open

$_phpinclude_output

Thoughts?
