openjdk with fedora 18/firefox 19

Sat Feb 23 14:03:35 UTC 2013

Is there an openjdk JRE plugin for Firefox 19 under Fedora 18?
Or have I misunderstood Firefox setup in some way?

All the test programs to see if Java is working
(eg http://www.java.com/en/download/testjava.jsp)
seem to look for Sun Java.
