Less messy than flickrs normal interface — although I had to do a stylish-script for it. I like to browse photos on black background. (Stylish might be my favorite Firefox-extension after Tabmix Plus and Keyconfig.)

@namespace url(http://www.w3.org/1999/xhtml);
@-moz-document domain("ihardlyknowher.com") {

body { background: #000 !important; color: #ffba00 !important; }
h1 * {color: #ff7a00 !important;}
a:link {color: #ff8a00 !important; font-weight: 700 !important;}
a:visited {color: #ff4a00 !important;font-weight: 700 !important;}
h2 {color: #ff0a00 !important;}

}
