The part that blocks Mr. Addy won't work anymore as the forum has been updated with an extra blank table row above mr addy.

Also CSS is probably a better way of blocking the ads.

Here's some css that works:

                
                
                @-moz-document	 url-prefix("http://www.syrnia.com/theGame/mainincludes/forum.php?pop=yes&action=viewtopic"),
                		url-prefix("http://www.syrnia.com/theGame/mainincludes/forum.php?pop=yes&topic=")
                {
                
                	table[width="100%"] > tbody > tr:first-child + tr,
                	table[width="100%"] > tbody > tr:first-child + tr + tr
                	{
                		display:none !important;
                	}
                }
                @-moz-document url("http://www.syrnia.com/game.php")
                {
                	#googleSearchContainer, td.leftTD > a[onclick][href=""]
                	{
                		display:none !important;
                	}
                }
