The Internets are filled with generous and pseudonymous people, one of whom, Aronnax, has given us GrApple, a set of four beautiful Firefox themes for Mac. I'm partial to GrApple Delicious (blue), which I think is the most beautiful browser theme I've ever seen. Yes, GrApple looks like Apple's Safari, but better. As Aronnax's page notes, GrApple looks "up to 3 times more beautiful than Safari and up to 5.5 times more beautiful than Opera 9." Thanks, Aronnax!
