Div hidden codes does not work!, it covers the ad in firefox Options

Div hidden codes does not work!
i this code and it covers the ad in firefox not in ie?
example of the code shown below

i take off all the codes in all the boxes like example: music, heroes, i will like to meet,about me ect.
then only leave the code that hides the myspace stuff to make the div only in the about me section and it still happens, only in firefox?


example:

CODE

<style>.mslogo, .clearfix form, .clearfix a, .clearfix select, .profileinfo, .contacttable, .userprofileurl, .interestsanddetails, .userprofiledetail, .userprofilenetworking, .userprofileschool, .userprofilecompany, .extendednetwork, .latestblogentry, .blurbs td.text, .orangetext15, .friendspace, .friendscomments, table div {display:none;}
table table div {display:block;}
div.profilewidth div {filter:alpha(opacity=0)!important;opacity:0;}
.profilewidth .clearfix, .profilewidth div div {filter:none!important;opacity:1;}
.profilewidth .clearfix {background:none!important;}
div[id="shortcuts"] {opacity:0!important;}
tr td .clearfix div {filter:alpha(opacity=0)!important;}
table, tr, td, clearfix {background-color:transparent!important;}</style>
