AutoPager is an extension for the Google Chrome Browser that lets you browse pages in a continuous manner. When you search for anything and you reach the bottom of the page, the next page will automatically get loaded without clicking anywhere else.
This functions smoothly and is a very good extension for Google Chrome Browser. By default, it works on the following websites:
Lifehacker, The New York Times, Digg, eBay, Amazon, Yahoo, YouTube, Flickr, Live, MSN, MySpace, Wikipedia, Taobao, Twitter and Google.
The extension is in its initial Alpha version as of now, but works quite nicely.
