Install Firefox Plugin Manually
When you install the Java platform, the Java plug-in file is included as part of that installation.
To use Java within Firefox, manually create a symbolic link from the plug-in file in the release to one of the locations that Firefox expects. To make the plug-in available to all users, you must create the link inside of the Firefox application's directory, in the plug-ins subdirectory. Alternatively, you can create the symbolic link in your home directory, in ~/.mozilla/plug-ins. In the remainder of this document, the text, Firefox plug-ins directory implies either of these locations.

For many, one of the biggest obstacles in Linux is installing applications. Because the computing world has grown so accustomed to click and install, the idea of having to manually install. I'm trying to manually install the Java plugin for Firefox 4 on Mac OS X v10.9 (Mavericks) (I got Firefox 4 from the PPA), but it seems the usual instructions don't work.
Note:
For Firefox version 21 and later, you must create the symbolic link in your home directory, ~/.mozilla/plugins. However, creating the symbolic link in the plug-ins subdirectory of the Firefox application's directory is not supported in Firefox version 21 and later.
This release provides the Next-Generation Java plug-in. The plug-in file for Linux is located at jre–9.minor.security.patch/lib/amd64/libnpjp2.so.

If you are using the classic plug-in file, which is located at ./plugin/i386/javaplugin-oji.so, then this file should no longer be used and all symbolic links to it must be removed.

but I still get the 'missing plugin' warning in Firefox. It used to work fine for Firefox 3.6. Also, after doing the first above, Chromium is able to pick up the Java plugin without problems. In case it makes any difference I'm running Oracle's 'vanilla' JDK, not the Ubuntu sun-java-6-bin package.

If you run the Oracle Java standalone installer (.bin file), it will just extract the java directory from the archive. It will not create the environment variable JAVA_HOME. It is best if you extract the java archive to a folder such as /usr/java.
Next, find the folder where Firefox is installed. It will have a directory named plugins there. In this directory, create a soft link to the file libnpjp2.so.
