am I at the right place

I had subscribe to this list with some intension and I dont know whether 
this is a right place to put such a question. If not please guide me to 
the right location.

I wrote some scripts in Rational Robot, which works great on IE, since 
IE expose it browser as a COM object and I can write automation script 
in Rational Robot (vb scripts). But as soon as I try to run them against 
mozilla, robot does not understand the mozilla browser control. And the 
main problem is Mozilla does not exposes DOM object thru MS-COM.(correct 
me if I am wrong)
I want to know whether I can write a COM object to identify each HTML 
element on the browser and ask the robot to do carry out certain action 
on the element.
For example: I may want the robot script to click on a certain link or 
type in some text in a edit box on mozilla, so if I can write an 
extension/plugin (I dont have much knowledge as of now) that can be 
pluged in mozilla to get me where on the screen the anchor reside, so 
that I can instruct the robot script to click on particular screen 
coordinates.

I want to know whether this is doable. If yes I can read more on this ..
If possible tell me am I posting this at right place ...
If you have any link/doc .. please mail me at
