Myspace Band Profile: Resize Comments Table and Columns

[realrealtomato]

I'm working on a Myspace band profile (version 1) and I need help resizing the comments table. It's looks right in IE (which I never thought I would say) but in FF it doesn't work- the right column appears to be just under 50% of the table width.

These are the dimensions I want
Table: 800px; Left column: 150px; Right column: 650px;

This is the page I'm experimenting with:

This is the code I'm using

<style>
table.friendsComments table, table.friendsComments td {background-color:transparent;border-width:0px;}

table.friendsComments span.orangetext15 {display:none}
table.friendsComments td.text span.orangetext15 {display:none;}
table.friendsComments td.text table {width:100%}

table.friendsComments td.text td td b {display:inline; margin-top:0px;}
table.friendsComments span.redtext {font-weight:bold; color:purple;}
table.friendsComments td.text td a {display:none;}

table.friendsComments td.text td.columnsWidening embed, table.friendsComments td.text td.columnsWidening object {width:260px; height:213px;}
table.friendsComments td.text td.columnsWidening img {width:300px;}
table.friendsComments .ImgOnlineNow {display:none;}
table.friendsComments td.text b {display:block; color:yellow}

table.friendsComments td.text b {
display:block; color:black; background-color:999966; height:20px; line-height:20px; text-align:center;}
table.friendsComments td.text td b a {display:inline; color:purple}
table.friendsComments td.text td b a:hover {text-decoration:none; color:666666;} 

table.friendsComments span.blacktext10 {color:999966; background-color:222222!important; display:block; text-align:center;}
table.friendsComments td.text td td.columnsWidening {background-color:333333;}
table.friendsComments td.text td td.columnsWidening a {color:99c9c9;}
table.friendsComments td.text td td {background-color:222222; padding-top:14px; margin-top:-20px;}
table.friendsComments td.text td td a {display:inline; color:999966;}
table.friendsComments td.text td td a:hover{text-decoration:none; color:996666;}
table.friendsComments td.text td td img {border-width:1px; border-color:black; border-style:solid;}
</style>

Thanks in advance for all of your help, Myspace's Frankenstein coding is just too much for me! :)
