Gigablast is the latest search engine to launch a toolbar for your browser. At first glance it seems rather Spartan when compared with other toolbars such as Yahoo’s and Google’s but it does have two unique and very useful features: search the sites linked from the current page and search the sites in your bookmarks. Unfortunately it is only available for IE at present. There is a plugin for Firefox users at http://mycroft.mozdev.org/download.html?name=gigablast&submitform=Find+search+plugins but this only adds Gigablast as an option to the built in search box.
