I have installed jdk and jre 1.6.0.24 on my Fedora 14 system (Firefox is 3.6.15). I've gone through all the instructions for installing the jre, I've even tried creating symbolic links in the various "plugin" directories for libnpjp2.so. Nothing seems to 'install' the Java Runtime as a Firefox Plugin. Suggestions? (java/javac/javaws are all working...)

Where are the other plugins installed that show in your More system details list ?

You can see the installed plugins on the about:plugins page.
If you set the pref plugin.expose_full_path to true on the about:config page then you see the full path of plugins on the about:plugins page.
It is best not to leave that pref set to true as it exposes that full path to web servers, so reset that pref to false after you are done with the about:plugins page.

What does the command "java -version" return? If it returns something like "OpenJDK Runtime Environment (IcedTea6 1.9.7)" this means that the Iced Tea is the default Java and that you will need to set Sun Java as the OS default Java. Fedora should have some details about that, it may require uninstalling Iced Tea Java.
