Firefox Extensions - communicating data over https

Hi experts.... a tough one I fear....

Lets assume the following.

Our user has a Firefox extension installed created by us.

First:       We need to activate this extension/plug-in on a page rendered using a secure protocol (https)?
Second: Can we then analyse information presented on that page and request the user to perform an action?

The key here I see is having the ability to process (with user interaction) over https

Your thoughts are greatly received, I look forward to hearing from you.

I'm not sure if I see where your problem is.
From within your extension's overlay.js you can (under appropriate conditions) change the currently displayed page via

Hi, Could you elaborate on your answer and just explain a little bit about how this could process information on a page rendered in https please?

I ask because I know very little about Firefox extensions at the moment. My training begins on Wednesday.

Thank you
I hope you know how to put up the basic framework of an extension after that training.
Once you know what th efollowing terms mean, you should be able to add a listener for the DOMContentLoaded event and in that you might inspect
var uri = getBrowser().selectedBrowser.currentURI;
and if it refers to the https page you redirected to, you can access the page content, e.g. via its DOM tree.
