I don't like it, its slow and the weirdest part is the border around the render window, sometimes its there and sometimes its gone, and it has still his problems with w3c rules/standards.
stick to Chrome, but I really dig the latest FF4 betas
It's faster than Firefox for me. In everything. And it gets a 95 on A3 whereas FF gets 97. There's no reason to even like Firefox when it's outdated and significantly slower than any other browser with the exception of IE, albeit both still in beta.
