After restart firefox once i installed the proposed yslow for firefox 3.5 i noticed a buggy behaviour : you can click in all buttons (grade , components ...) it don't work and only give you the performance mark 0 or 100 . If anyone who either installed this version has the same problem or is it only me ?
p.S : does PageSpeed addon (same than yslow but by google) only suggest rules to tweak the page load time or can it change rules of page loading (like Ylows rulests V2 instead of Classic V1) ?
