With the Google Autopager for Greasemonkey (a Firefox extension) you can safely forget about the “next” button below the search display pages: when you do a google search and scroll down towards the bottom of search results, this script will seamlessly retrieve the next set of results and display them on the same page.
You’ll get an “infinite” scrolling and searching will be way faster!
