Nice! if you change @-moz-document url(chrome://stylish/content/stylish.xul) to @-moz-document url-prefix(chrome://stylish/content/stylish.xul) it now becomes sidebar friendly
It gets even better I added url(chrome://stylish/content/stylish.xul?sidebar=1) after the first url and now I've got dots in my sidebar! This things just keeps getting better and better! A must have!!!!
