Firefox Extension that lists links and scrolls

I need C# code that will allow me to interface [firefox 1.0][1] to do the following: 1) list all of the visible links on each frame in focus. You can list all of the links including image maps on the entire page but i need a way to know which one's are currently visible to the user. I need to have access to the text/alt tag as well as the url for each link and the screen rectangle around each link. 2) buttons to scroll up, down, left and right. I need to be able to adjust the scroll stepping as well as make it autoscroll at an adjustable speed. ## Deliverables A working program and it's source that that meets all requirements and is heavily documented using the XML commenting style.
