Java is installed and enabled for Firefox 3.6.9 on my Linux system, but Java does NOT appear in my Tools/Add-ons/Plugins window. How can I Enable it?

The Java console shows the JRE properly set up for my default browser, Firefox. However, neither Java nor JRE appears in the Tools/Add-ons/Plugins window, and your test site and others show that Java is not enabled for my Firefox 3.6.9 browser. So, what is the problem, and how can I fix it.

In Firefox 3.6 and later versions you need the Next-Generation Java™ Plug-In present in Java 6 U10 and later (Linux: libnpjp2.so; Windows: npjp2.dll).

You can use a symlink like this one to a location that Firefox scans for plugins: 

ln -s /usr/lib/jvm/jre/lib/i386/libnpjp2.so /usr/lib/mozilla/plugins/libnpjp2.so (java-1_6_0-sun-plugin)

cor-el,

Thank you for your assistance. Your recommendations did the trick. I might add though that upgrading to Java 6 U10 was not enough. At first I upgraded from Java 6 U02 to Java 6 U11, and it still did not work the problem. So, I upgraded to Java 6 U20, and that worked. In Slackware, that meant upgrading two packages; namely to jre-6u20-i586-1.tgz AND jdk-6u20-i586-1.tgz .

Thanks again, -- William
