Nav Buttons Bar FF Glitch

[Judger21]

Hello,

I'm having issues determining what is causing a minor glitch on my website. My navigation buttons bar is a little out of line when viewing my website on FireFox. I've done a lot of modifying and I'm not sure where it happened.

I also have went through the backup code and didn't find any irregularities.

Attached is a SS of the glitch. The navbar is in line perfectly on other browsers.

Below is also my navbar code. I'm guessing it's a css issue but I'm not sure why it would affect only one browser.

<!-- nav buttons bar -->
<tr>
	<td style="border: none; padding: 0;"><table border="0" cellspacing="0" cellpadding="0" width="100%">
	<tr>
		<td width="9" align="right" valign="bottom"><img src="$stylevar[imgdir_misc]/nav_top_left.gif" width="9" height="2" border="0" alt="" /></td>
		<td width="100%" class="navbar-top-row"><img src="$vboptions[cleargifurl]" width="1" height="3" border="0" alt="" /></td>
		<td width="9" align="left" valign="bottom"><img src="$stylevar[imgdir_misc]/nav_top_right.gif" width="9" height="2" border="0" alt="" /></td>
	</tr>
	</table></td>
</tr>
<tr>
	<td class="navbar-row" align="center"><table cellpadding="$stylevar[cellpadding]" cellspacing="0" border="0" width="100%" align="center" class="navbar-row-table">
	<tr align="center" class="vbmenu_dark">
		<td width="9" align="right" style="padding: 0;"><img src="$stylevar[imgdir_misc]/nav_left.gif" width="9" height="21" border="0" alt="" /></td>
		<if condition="$show['member']">
			<td class="vbmenu_control"><a href="/index.php">Home</a></td>
			<td id="mypopupmenu" class="vbmenu_control"><a href="#mypopupmenu">Forums</a> <script type="text/javascript"> vbmenu_register("mypopupmenu"); </script></td>

Any help would be appreciated!
