How to make a firefox addon that acts as an offline website

What I want to do is that when the user clicks a button I will add to firefox (or clicks an option I will add under tools, etc), a new tab should be开发者_JAVA百科 opened, and in the tab will essentially be an offline website that is written in HTML/CSS/JS and will be part of the addon.

How can I do this? It does not matter to me if I require a very new version of firefox to accomplish this.

Making your first firefox addon can be quite challenging, at first. But once you make one, things get much better. Here are some tools to help you get started:

I suggest you start with this and check all the features. Once you download the skeleton, look over ff-overlay.xul in the /chrome/content folder. It should be straightforward if you know XUL/Javascript.

This link helps you set up Firefox for easy addon testing and debugging.

The Mozilla Developer Network is incredibly useful. For example, that link takes you to a page that explains everything about switching tabs.
