How do I get the SUN Java plugin to work in Firefox 8.0 or Seamonkey 2.6?

After a recent automatic upgrade of Firefox on my Xubuntu 11.04 system, the SUN Java plugin is no longer recognized by Firefox. I tried the old method of manually symlinking the corresponding library to /usr/lib/mozilla/plugins and various other directories that contained plugins, but to no avail. Other plugins like Flash work fine. Having the SUN Java plugin working is a must for me in order to be able to access my online bank, the Citrix server at my workplace, etc.

Try to create a plugins folder in the Firefox Profile Folder and place a symlink to the JP2 Java plugin file (libnpjp2.so) in that folder.

You can use this button to go to the Firefox profile folder:

Also, Exit Firefox and rename the pluginreg.dat in your profile folder and start Firefox again. This may help to reinitialize the plugins that Firefox recognizes.

cor-el and Vivek.Wilfred,

Thank you very much for your swift replies! In the end, I managed to solve my problem for all users of my computer at once by creating a symbolic link in the directory /usr/lib/firefox-addons/plugins to the file /usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so. the two important points were (1) to use libnpjp2.so instead of the file libjavaplugin_oji.so, as indicated on http://plugindoc.mozdev.org, and (2) to put this into /usr/lib/firefox-addons/plugins.
