In Firefox 16 configuration is the following value:

browser.newtab.url: about:newtab

What are other possible values here? In Mozilla knowledge base only the values about:newtab and about:blank are mentioned. Is there something to load the currently set homepage?

You can put any URL there, e.g.

There is no link to the homepage in the about:-scheme, but you can enter your homepage manually, of course.

One thing you might be interested in putting there is about:home, that will give you the default homepage of Firefox. You'll find a list of all about:-pages here.

But this will not use the currently set homepage. Is there something generic? – Martin Nov 3 '12 at 12:15
It is no longer possible to do this. One solution is middle-clicking the home-button instead of opening a new tab. Or you can just install a browser extension. – L3viathan Nov 3 '12 at 12:18
