AutoPagerize is a must-have Greasemonkey script for multi-page search results
Lee wrote about AutoPagerize back in September 2009. Now, almost one year later, the userscript is still going strong. It was updated in March of this year, and it now has a dedicated version for Chrome.
Its function is as simple as it is useful; it loads the next page of results in Google without you having to click anything. Just continue scrolling down the page, and the new results will show up. It's magic!
It works that same type of magic on numerous other sites, too (Download Squad included). Ever since I installed it, I haven't felt the need to press the Next button even once (well, except in Gmail). It's very, very convenient.
There are a ton of dedicated browser extensions that do this (as well as a few other userscripts). Personally, I prefer a userscript to an extension because it's just a leaner solution (in terms of lower memory consumption and general overhead). I can honestly say that it has transformed my Google experience. And more than half a million installations would seem to concur.
