New page - no ajax? but ajax? [duplicate]

Question

Look at this page: https://github.com/mozilla/chromeless/tree/master/examples/first_browser

When I browse between the folders and files, my browser changes the complete url. No Hashtag found like in other jQuery-ways. A whole new page..

But how to change the complete Page and not reloading it?

Thanks for your answers.
