All of that is going to vary from system to system. For example, my
system has /usr/lib/firefox-<version>/
and /usr/lib64/firefox-<version>/, but a lot of systems avoid the
version mess and use /usr/lib/mozilla/plugins/. Also, keep in
mind /etc/alternatives/.

No, you don't need the full JDK, just the Sun Java Runtime Environment
and plugin packages. The JDK has a ton of unnecessary development
specific content that will make for a longer download and more cruft on
your system.

In Kubuntu, you should be able to install it from the standard apt
repositories from the package "sun-java6-plugin". You then need to
update your system's configuration to use that JRE by running the
following command with root privileges:

update-alternatives --config xulrunner-1.9-javaplugin.so

See the following for further instructions if that doesn't work.


Once that's done, go to about:plugins in Firefox and check the path
