I am running Fedora Core 6. Core 6, coming out of the box runs Firefox version 1.5 I up graded it to version 2.0 This was early days in my use of the system. I did not know how to upgrade properly, and probably still do not as I have to let yum do it automagically. I found out afterward that Fedora does not like and is not supporting version 2.0. I don't know exactly where the new version of Firefox went to. RPM put it somewhere. I have managed to set up shortcuts to it that work to launch version 2.0.0.3 . When the system launches the program it launches Firefox version1.5. Into this mix I am trying to get Java plugin to run in Firefox 2.0.0.3 . Per the web site I am supposed to create a symbolic link to the java .so file "libjavaplugin_oji.so" This is in the download directory which in turn is in my home directory. It is there because I do not understand how Linux handles the files as to where they are supposed to be stored. In spite of many hours of research, I still find my self very ignorant. It almost looks like it does not matter. If this the case I stand astonished. At any rate, per instructions from Mozilla I created a symbolic link to the target file and put it in the .mozilla/plugins folder. After restarting Firefox, I still do not find java in my plugin window "Tools | Add Ins" I can see many things I may have done wrong, but I am not sure how to fix them. I would like to get Java running so I can participate in Alan's Robocode demo. Harold
