I've been doing some work with the Mozilla project, and I can confirm
this. All of their user interface stuff is cross-platform-ified using XUL,
and styled by CSS, with functionality provided by JavaScript and some
infrastructure to connect XUL/JS events to compiled code.

You can have a look at Ben Goodger's XUL work (he is the accepted XUL guru
of the Mozilla community, as far as I can tell) at:

Just browse through the images there.

Of course, I don't know what this has to do with XSL either...
