One suggested addition - if you are using the black box search plugin for Greasemonkey (routes all your Google searches through an anonymous proxy), add the following URL to each of the lists of @-moz-document url sections: url-prefix(http://www.blackboxsearch.com/cgi-bin/search.cgi)
Otherwise the search results default back to the regular Google look.
