Because of heavy changes on Digg web site, this script isn't working anymore. As a replacement, add the following CSS codes to userContent.css or Stylish extension.
@-moz-document domain(digg.com) {
#h-sec .h-drop:hover > .submenu-drop,
#h-sec .h-drop > .submenu-drop:hover {
display: block !important;
}
.submenu-drop {
padding: 0 10px !important;
margin-top: -5px !important;
}
.submenu-drop > li {
margin-top: 0 !important;
}
.submenu-drop > li:first-child > a {
border-top: 0 none transparent !important;
}
}
