Manipulation

So, I've made an AutoHotkey script that clicks links on a webpage from using PixelGetColor, and it works well, but I have to give up access to my mouse while it's running. So, I'm looking into making a script that loads a webpage in the background and clicks the links without moving the mouse. The links need to be clicked, as the URL changes every time, and that just can't be copied, it needs to be clicked. Any ideas on where I should get started?

tl;dr: I want to make a program to manipulate webpages in the background.
