====== Install the Java-Plugin for Firefox ====== To install the Java plugin for Firefox, you have to create a symlink from Firefox's plugin directory ''/usr/lib/firefox-addons/plugins/'' to the file ''libnpjp2.so'' in the JRE's "lib" dir. sudo ln -s \ ${JAVA_HOME}/jre/lib/amd64/libnpjp2.so \ /usr/lib/firefox-addons/plugins/libnpjp2.so Please note, that I tested this with Ubuntu 14.04, the "plugin" directory may be somewhere else on your system. {{tag>java plugin linux ubunutu sysadmin}}
