I installed latest firefox 64 bit (22 April 2011) on my SUSE Linux laptop. I spent hours trying to enable the java plugin. Seems that tools has been changed and does not have any java entries. All the online documentation is totally obsolete. I used Google and found one entry for CentOS that just happened to work. You have to create a directory /usr/lib64/firefox/plugins and in it add a link to the libnpjp2.so file in your java distribution. I am using the sun distribution from oracle and it works just fine.

A 64 bit Firefox needs 64 bit plugins. 64 bit Firefox versions from the Mozilla site are currently only created to test if compiling the code works and aren't tested that well.


You can check if you see the Java plugin in the Tools > Add-ons > Plugins window.
