It means, what if I reference "eb" with some edit-form on "ebay.com" and after that tap in address bar "eb spider-man comix", browser will search "spider-man comix" via ebay-search. I also able to create any additional search-strings: for wikipedia, trackers, film-sites and others. Is there any serach mechanism in FireFox like that? Or maybe some plugins?.. I really need this.
