Gecko/Firefox uses cairo to replace their own custom drawing routines
that implements the drawing part of the gecko API. Firefox extensions
use the gecko API (or XML/JS/SVG/etc), so the switch to cairo is

Plugins eg: flash, java use a platform window handle or platform
surface directly that they get through the plugin API that is called
NPAPI. So in that case those plugins do not use cairo at all. see
http://en.wikipedia.org/wiki/NPAPI and

My understanding comes from reading the mozilla code and blog entries,
so I may be somewhat wrong :-)
