You can assign keywords to alternate search engines in Firefox. Apparently there's an extension for the scrollbar thing (https://addons.mozilla.org/en-US/firefox/addon/highlightall/ https://addons.mozilla.org/en-US/firefox/addon/highlightall/) although I can't quite imagine why it would be more useful than just visiting the search results sequentially.
