Better Mobile Twitter user script

I always keep a tab in Firefox opening Twitter and I prefer the mobile version instead of the standard one for speed and simplicity. Despite the simplicity, one thing I would like to have is automatically load next page when the mouse scroll to bottom (just like what Google Reader does). As a result I come up with the Better Mobile Twitter user script. You can install in http://userscripts.org/scripts/show/35396. Below is showing how it works, or you can watch in high quality.
