Firefox is fast - firefox is on FaYYaaa! :D\n\nThe footer image is only visible on Firefox 3.0..Because Firefox Personas need I think a little bit more fixing in their program :)\n\nThe skin is made totally by myself in photoshop CS2. The fire is made by me, using a nice tutorial. Who wants the PSD - speak!"
