Just posting a shot of the clean desktop of the user account I use for internet mostly.
OS theme is BBX Murcury X and Mozilla Firefox theme is mercnvert by lynchknot. Been to lazy to hack the mercnvert.jar to skin scrollbar properly since I now have a computer that can handle the extra skinning without taking a hit.
The three icons on top left is Compact menu, X (aka:Paranoia) and ChromEdit extensions. I changed the look of the first two in userChrome.css. Easier and quicker than hacking the extensions themselves.
