css - CSS4 Selectors and browser

Question

I would like to test (reason : just curiosity) CSS4 selectors and particularly the CSS pseudo-class :not() with a selector list (cf. code and Select first element which is placed after another element but not immediately). Is there a beta version of a browser to do that (OS : windows or Linux) or should I wait quietly ?

h1:first-of-type ~ h2 :not (h1:first-of-type ~ h2 ~ h2) { color:red;}
