Pandoras Jar is written in java and therefor requires the java runtime environment and firefox. Download Pandoras Jar from the link given above and unzip it into a directory of your choice. Run pandora.jar, if a little window (Pandoras Jar) appears Java is working fine and you are ready to fire up firefox and enter localhost in the address bar and hit enter.
