Java plugin on Linux
On a supported Linux (on Ubuntu versions less than a year old unless it is a LTS version):
In a shell window type:
sudo apt-get update
sudo apt-get upgrade
(this will of course only work if 'openjre' is installed)
How to link to the java plugin manually on Linux systems where update is not possible:
Download the latest tar file from: http//java.com
Click on "Download"
Download the Linux tar file appropriate to your browser (32 or 64 bit)
Ex: the jre-7u7-linux-i586.tar.gz file has been downloaded to the '/tmp' folder.
Install in '/usr/local':
cd /usr/local zcat /tmp/jre-7u7-linux-i586.tar.gz | tar xpvf -
After unpacking link to the java lib file:
cd /usr/local/firefox/15.0/plugins (if the 'plugins' folder do not exist then create it)
ln -s /usr/local/jre1.7.0_07/lib/i386/libnpjp2.so .
Restart the Firefox browser (all old instances must be killed) and type this in the URL field:
