Starting in Firefox 3.6.7 (I think) the (Sun) Java plugin changed names. 
Here is what it should look like ...

$ ls -la /usr/lib/mozilla/plugins/libnpjp2.so
lrwxrwxrwx 1 root root 37 Jun 24 19:32 
/usr/lib/mozilla/plugins/libnpjp2.so -> /usr/java/latest/lib/i386/libnpjp2.so

The plugin name changed .. the old one plugin is still in the jdk, but 
will silently fail in the browser.

Hope this helps.
