Still not working for me using FF 14.0.1, Firebug 1.10.2 and Yslow 3.1.4. As others have described, Im can click the Yslow Icon only to be treated with a blank box, clicking on Run Yslow won't do anything, clicking on Close will close the box.
EDIT: If I open the firebug tab and then navigate to Yslow, I can use it just fine.
