Auto Page Scroller Script

Job Description

I need a simple script that will make a webpage automatically start scrolling to the bottom of the page. When the page gets to the bottom, it should return to the top, pause about 5 or 10 seconds, then start again and do this continuously.

Firefox has an add-on called Scrolly Fox that is exactly what I need, and I use it when browsers are using Firefox. But I need this script to work on all browsers and with tablets as well as PCs.
