SearchFox, as Steve Rubelsays it is a new search engine/tagging tool it's a mix of Google + del.icio.us + MyWeb 2.0 + Firefox. With SearchFox you can add your favourites typing, using the toolbar or searching; save them with description and tags; share them; import your browser favourites; preview the search; subscribe links, groups and people; publish lists of bookmarks on your blog and build a searchable blog index; and access from any computer. Very cool isn't? I just have one problem about start to use it: 4025 items saved on my del.icio.us.
