With IRobotSoft Visual Web Scraper, you are able to visually record web scraping actions.

Answer 3

I don't know what kinds of tasks you are looking for... but this sounds like a Firefox extension you are trying to build and automate.

I would look at those docs to see how you can attach to the main browser window and track those click and keyboard actions.
