With the Firefox Extension "CustomizeGoogle", you can enable Favicons on all Google Searches. The problem is that on sites that Do Not supply one, CustomizeGoogle supplies a generic favicon.
I really dislike Generic Favicons, so this style removes them, making the sites without a favicon stand out more.
