How do I close a browser tab when the scrollbar reaches the bottom of the page?

Question

Using Autohotkey, I’ve remapped a button to execute a loop. Every 30 seconds, PgDn will execute. In order to move on to the next tab, Ctrl-W (close tab) needs to happen. Is there way any to detect that the scrollbar as at the bottom? Once the “scrollbar-at-bottom” condition is met, PgDn will execute “close tab” instead. What language should I learn to make a program/script that can do this? I know a little bit of Java. Can Javascript do this?

Thanks

You probably need to investigate building a Firefox extension.
