Firefox has been my default browser for years now. With the advent of their extension system, I thought I’d never leave. But the introduction of Safari 4 has changed all that.
I did love my extensions, but the functionality and sheer elegance of the Safari 4 interface has converted me yet again. Not to mention the (albeit slight) speed increases. Designers should download it if only to have another test browser in their arsenals. But for the rest of you, do it for the experience. And enjoy 😉
