Thanks for the detailed instructions. I have never heard of xulrunner. Something of that name was installed but I installed a newer (?) version using synaptic. I also used update-alternatives to get java to point to the sun version. Now I have this:
j...@ubuntu%sudo update-alternatives --display java java - status is manual. link currently points to /usr/lib/jvm/java-6-sun/jre/bin/java /usr/lib/jvm/java-6-openjdk/jre/bin/java - priority 1061 slave java.1.gz: /usr/lib/jvm/java-6-openjdk/jre/man/man1/java.1.gz /usr/bin/gij-4.2 - priority 42 slave java.1.gz: /usr/share/man/man1/gij-4.2.1.gz /usr/lib/jvm/java-6-sun/jre/bin/java - priority 63 slave java.1.gz: /usr/lib/jvm/java-6-sun/jre/man/man1/java.1.gz Current `best' version is /usr/lib/jvm/java-6-openjdk/jre/bin/java. j...@ubuntu%sudo update-alternatives --display xulrunner xulrunner - status is auto. link currently points to /usr/bin/xulrunner-1.9 /usr/bin/xulrunner-1.9 - priority 50 /usr/lib/xulrunner/xulrunner - priority 50 Current `best' version is /usr/bin/xulrunner-1.9. I don't know what 'best' means, it still seems to like the look of the open jdk for java. After all this and restarting firefox there is still no mention of java in about:plugins. I find it hard to believe that it is not there since the Preferences setting for jave is enabled" and surely there are many other web things which would not work without java (gmail for a start). The jmol demo page shows exactly the same message as before.
