I just upgraded my Firefox to 3.6 and had a lot of problems getting my java plugin to work with the new version. Most of the instructions about installing the symbolic link state something like

ln -s <path to>plugin/i386/ns7/libjavaplugin_oji.so

but this does not work. It seems the filename has changed, so something like

ln -s /usr/java/jre1.6.0_1x/lib/i386/libnpjp2.so

is needed.
