Hiding Myspace url in Firefox without the white box Options

[bedhead]

I'm having problems hiding my url in Firefox, even though it works fine in Safari. For some reason, there's a white background in back of my url that I can't make go away. I've moved my music player to cover it, but it's still peeking through at the sides. Here's my page for reference.

Here's the code I'm using to block the url and to move the music player up:

<style type="text/css">td td embed {position:relative; top:-42px; display:block;width:295px !important; background-color: 990000;}td td td embed { position:static; width:auto !important; }</style>

<style type="text/css">
table table table table div {visibility:hidden;}
div table table table table table div input, div a, td.text div {visibility:visible;}
</style>

Also, the music player doesn't reposition in Safari like it does in Firefox. Is there a solution for that as well?

Thanks in advance!
