Javascript Question

I am finding a way to preform tasks on a facebook page quickly. The process involves clicking through various menus and is time consuming. I’m thinking of either developing a chrome app or writing javascript code to streamline the process. Does anybody have any experience creating code for use within facebook? Should I try working with chrome or firefox utility extensions?

Any advice greatly appreciated.

What is it you are trying to do exactly?

I tend to use Mechanize when I want to accomplish website automation.
