Do you notice that bottom borders in some <td>
and <tr>
elements are thicker in Firefox compared to Chrome and Opera?
table.mytable td {
border: 1px solid black;
}
<table class="mytable">
<!-- Table Code Snippet -->
</table>

It seems that the bottom borders of the first, fifth, and ninth TRs appear thicker. Even using the attribute border=1 in the table tag doesn't solve this issue.
Edit: I am viewing the page at 100% zoom on Firefox.
