[ SOLUTION SOLVED ]
Here is the solution.
Download the latest Java Runtime Environment at the time of writing this [2010/March/11]it was jre-6u18-linux-i586.bin. I have a 32 bit install of Debian Lenny environment.
Move the file to this directory /usr/lib/jvm/ if it does not exist create it like this.
sudo mkdir /usr/lib/jvm/
Move the downloaded plug-in to “/usr/lib/jvm/ “
sudo mv jre-6u18-linux-i586.bin /usr/lib/jvm/
Change to where you moved the file
sudo cd /usr/lib/jvm/
Make it executable
sudo chmod a+x jre-6u18-linux-i586.bin
Hit enter until you get to the end of the you better agree to this stuff and type “yes”
sudo update-alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so mozilla-javaplugin.so /usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so 50
Go to Firefox plug-ins install directory. This might not be the same place as mine “/opt/firefox/plugins”
sudo cd /opt/firefox/plugins
Make a symbolic link in your Firefox install directory
sudo ln -s /usr/lib/jvm/jre1.6.0_10/lib/i386/libnpjp2.so
You will see the time.
You can do this also but it did not work for me.
“If you install Firefox 1.5 or later, you can enable the Java Console menu item in the Tools menu. Change directories to the Firefox extensions directory, then unzip ffjcext.zip there.
