If you use WebCenter Sites on Linux with Firefox, you may have hit the nasty issue where the latest Firefox update disabled your tools. These are the steps I followed to get it working again:

1. Locate your Mozilla installation plugins directory. In the example below, it is at /usr/lib64/mozilla/plugins
2. Locate your Java home. In the example below it has been set as the system variable JAVA_HOME
3. Go to the plugins directory and sudo as root
4. Create a symlink to the Java plug in
5. Important! Exit root before performing the next step or the plug-in will only be enabled for root.
6. Run jcontrol and sites you need to run the plugin to the security exception list

Example commands:

[myusername@ol6vm]$ cd /usr/lib64/mozilla/plugins
[myusername@ol6vm plugins]$ sudo su
[sudo] password for myusername: 
[root@ol6vm plugins]# ln -fs $JAVA_HOME/jre/lib/amd64/libnpjp2.so libnpjp2.so
exit
[myusername@ol6vm plugins]$ $JAVA_HOME /jre/bin/jcontrol
