It uses both gtk2 and cairo, just like firefox-2.x. The widget toolkit
is gtk2, but any graphics rendering it does on its own is via cairo.
Here's the key sections of configure:
_PLATFORM_DEFAULT_TOOLKIT=cairo-gtk2
...
cairo-gtk2|cairo-gtk2-x11)
MOZ_WIDGET_TOOLKIT=gtk2
MOZ_GFX_TOOLKIT=cairo
MOZ_ENABLE_GTK2=1
MOZ_ENABLE_XREMOTE=1
AC_DEFINE(MOZ_X11)
MOZ_X11=1
TK_CFLAGS='$(MOZ_GTK2_CFLAGS)'
TK_LIBS='$(MOZ_GTK2_LIBS)'
AC_DEFINE(MOZ_WIDGET_GTK2)

If firefox is using xulrunner, then it just relies on that for all the
mozilla APIs, including graphics. That's the major reason for
xulrunner. So, if you built xulrunner to use the system cairo, then
that's also what firefox will use.
