How to register my own Firefox extension?

Question

I am trying to learn how to write Firefox extensions. I download the HelloWorld example from here , but I cannot figure out how to register it.

I found a folder with profile extensions (just because I use the latest version of Firefox), but I couldn’t understand what the “pointer file” I needed to create (tried a shortcut, but it didn’t work).

What is this "pointer file"? How can I register it correctly? I use Win 7 if that matters.

Thank.
