How to Update Java Plugin

Taken from java.com website.

Enable and Configure

Firefox or Mozilla

To configure the Java Plugin follow these steps:

1. Exit Firefox browser if it is already running.
2. Uninstall any previous installations of Java Plugin.
   Only one Java Plugin can be used at a time. When you want to use a different plugin, or version of a plugin, remove the symbolic links to any other versions and create a fresh symbolic link to the new one.
3. Create a symbolic link to the libnpjp2.so file in the browser plugins directory
   • Go to the plugins sub-directory under the Firefox installation directory
     cd <Firefox installation directory>/plugins
   • Create the symbolic link
     ln -s <Java installation directory>/lib/i386/libnpjp2.so
   
   Note: If you are upgrading your Java version then before creating new symbolic link you should remove old symbolic link to enable latest downloaded Java.
   
   To remove old symbolic link:
   type cd <Firefox installation directory>/plugins
rm libjavaplugin_oji.so
   

   ---

   Example
   • If Firefox is installed at this directory:
     /usr/lib/<Firefox installation directory>
   • And if the Java is installed at this directory:
     /usr/java/<Java installation directory>
   • Then type in the terminal window to go to the browser plug-in directory:
     /usr/lib/mozilla/plugins#
   • Enter the following command to create a symbolic link to the Java Plug-in for the Mozilla browser.
     ln -s /home/Pretorians/Documents/Installer/jre1.7.0_25/lib/i386/libnpjp2.so
   
   

   ---

4. Start the Firefox browser, or restart it if it is already up.
   
   In Firefox, type about:plugins in the Location bar to confirm that the Java Plugin is loaded. You can also click the Tools menu to confirm that Java Console is there.
