is 0.6.3 working in ff 6,0,1 ? Rated 5 out of 5 stars

hi there i'm a huge fan of LR, but since i'm using it i have to work in safari/chrome since i can't activate it in ff 6.0.1, i enabled the icon in my addon bar, but it is always greyed out, did i missed something ?

This review is for a previous version of the add-on (0.6.2.1-signed).
