I have no problems with it in FF at all. Here's my entire jukebox_mediadisplay template. Keep in mind that I cut a lot of stuff out of it, but see if it helps:
Code:
$stylevar[htmldoctype]
<html dir="$stylevar[textdirection]" lang="$stylevar[languagecode]">
<head>
$headinclude
<title>$vboptions[bbtitle] - $vbphrase[jukebox] - $vbphrase[jukebox_view_media]: $media[title]</title>
</head>
<body>
$header
$navbar
<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">

<td class="tcat" width="100%" colspan="2">$vbphrase[jukebox_view_media]<span class="normal"> $media[title] by $media[author]<if condition="$bbuserinfo['usergroupid'] ==6"> | <a href="$vboptions[bburl]/$admincpdir/jukeboxadmin.php?do=editmedia&mid=$media[mediaid]">Edit</a> | <a href="$vboptions[bburl]/$admincpdir/jukeboxadmin.php?do=deletemedia&mid=$media[mediaid]">Delete</a></if></span></td>
<if condition="$can['rate']">

The one thing really killing me with this hack is the lack of usergroup file-count permissions. There's nothing really stopping a new user from signing up and uploading 500 megs of stuff.
