Hi I have tried to link .mozilla/plugins/libnpjp2.so to the following (one at a time) /usr/jre1.7.0_65/lib/i386/libnpjp2.so ./usr/java/jre1.7.0_65/lib/amd64/libnpjp2.so ./usr/jre1.7.0_13/lib/amd64/libnpjp2.so I also removed .mozilla/firefox/aiwbua32.default/pluginreg.dat so it can regenerate a new one. Still out of luck. When I go to Tools->Add-ons->Plugins, I just do not see java there. Am I missing anything? Thanks
