Hi there
It's not a complaint just a note: when I hover over the adds on DW pages my Firefox often crashes (and says 'Well, this is embarassing...'). I learned to live with that (patience is my strong attribute) but thought you might want to know (also I do not want to embarass Firefox too much).
My Firefox is 15.0.1 (some older versions were crashing, too) on Fedora 17 64bit.
