Whenever anyone has asked me if I was going to a Firefox theme, I tell them there’s no point. There’s a chap called Aronnax, who has created some beautiful themes that make Firefox feel a whole lot more like a Mac product.
Recently, his site at spymac has been down a lot, so I offered him the Take back the web.org site as something more reliable. I felt it was so important that his themes are as available as possible, as they really make Firefox liveable on a Mac. He’s redesigned too, take a look.
The old Firefox wallpaper is still available.
