I have built an internet kiosk and I require an extension which does the following using Firefox.
1. Divides the screen into three areas, the top and bottom portions each using 15% of the total viewable area.
2. The top and bottom sections display a .jpg and alternates every 30 seconds.
3. The middle is used for regular browsing.
4. The .jpg areas need a configuration file so I can change where they are being viewed from (different websites).
