Autopagerize adds infinite scroll functionality to hundreds of websites, including Google, Yahoo, Blogger, and Twitter. It was written by Japanese hacker swdyh with inspiration and ideas from ma.la. I strongly recommend you check it out. Naturally you’ll need the Firefox extension Greasemonkey in order for it to work.
If you’re not a greasemonkey type of person, you can install the AutoPager firefox extension.
If you’re an IE user, please get yourself a better browser and I’ll think about forgiving you..
