I have this code in part of a table:

<td width="41" height="25" bgcolor="#99CCFF"><p><strong>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</strong></p></td>
    <td height="20" colspan="3" bgcolor="#99CCFF">&nbsp;</td>
    <td height="20" bgcolor="#99CCFF">&nbsp;</td>
Its from here: http://www.access-programmers.co.uk/...isplay.php?f=6

Look just below the tabs using Firefox and you can see the blue bar is taller than if you go to the homepage of my site. If you look using IE its always the same height.

What is wrong with my code that causes this anomaly?
