I use:
Script (JRE only)

Only supports Oracle (Sun) Java 7 JRE (which covers the needs of 99 % of
all computer users). It pulls the packages from Oracle's website and
installs them, comparable to the way Adobe Flash Player is being
installed. Plus it adds a dedicated repository, from which you'll
receive updates automatically.

Java 7 works fine with Firefox, but as a heads-up it does not with
SeaMonkey:

[[linux] Sun Java jre1.7.0_04/_05 does not work in SeaMonkey]

You might consider just giving in and installing openjdk & icetea instead.
