I am running firefox 3.6.8 on linux. I have also installed jre 1.6. When accessing one intranet website, firefox keeps saying "this feature requires jva 1.6 to be installed on your system...". I have installed java 1.6. I have made following symbolic links already: 1. /usr/local/mozilla/firefox/plugins/libjavaplugin_oji.so to /usr/local/jre1.6.0_21/plugin/i386/ns7/libjavaplugin_oji.so.

2. /usr/lib/mozilla/plugins/libjavaplugin_oji.so to /usr/local/jre1.6.0_21/plugin/i386/ns7/libjavaplugin_oji.so.

Emptied the cache. Restarted firefox. But getting same error message " this feature requires java 1.6 to be installed..."

Does this site confirm you have java 1.6?

That is not the correct Java plugin: libjavaplugin_oji.so

In Firefox 3.6 and later versions you need the Next-Generation Java™ Plug-In present in Java 6 U10 and later (Linux: libnpjp2.so; Windows: npjp2.dll). 

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)
mv
mv

This worked for me (on xubuntu):

sudo update-java-alternatives -s java-6-sun

It used to work before. Probably some update messed up the settings? I also completely removed that *$#&! useless OpenJDK. But donno if that made a difference.
