highlight nofollow links

In your ~/.mozilla/firefox/.../chrome/userContent.css:

a[rel~=“nofollow”] {
 border: thin dashed firebrick ! important;
 background-color: rgb(255, 200, 200) ! important;
}

I had no idea CSS could do such fancy selectors!

Test it by clicking around on fexweb and looking for the red background on links.
