On Debian installed SUN-JAVA6-JRE and IA32-SUN-JAVA6-BIN and vanilla Firefox 3.6.6

Followed instructions to create symlink libjavaplugin.so -> /usr/lib/jvm/ia32-java-6-sun-1.6.0.20/jre/plugin/i386/ns7/libjavaplugin_oji.so in ~/.mozilla/plugins, but restarting firefox and about:plugins does not show Java plugin.

Also created symlink in /usr/lib/mozilla/plugins, and in firefox install dir /usr/local/firefox/plugins. but none of this solved the issue.

Please advise

Chosen solution

In Firefox 3.6 and later versions you need the Next-Generation Java™ Plug-In (libnpjp2.so; present in Java 6 U10 and later). 

ln -s /usr/local/java/jre1.6.0_20/lib/i386/libnpjp2.so libnpjp2.so
ln -s /usr/lib/jvm/jre/lib/i386/libnpjp2.so /usr/lib/mozilla/plugins/libnpjp2.so (java-1_6_0-sun-plugin)

It took me a while to even find the libnpjp2.so plugin. Sun/Oracle no longer put it in the plugins directory in their download, but in the jre/lib/i386 directory. You will need to link from /usr/lib/mozilla/plugins to the installed location.
