Important: Mozilla adds outdated or insecure plugins to its Add-ons Blocklist as a security measure. Starting in Firefox 3.6, Java will not work unless you are using the Next-Generation Java Plug-In (included in Java 6 Update 10 and above). See JavaScript is not Java for more information. Note that Java is not the same as JavaScript. To run these Java applets, you need the "Java Runtime Environment" ("JRE") installed and enabled. Many web pages use Java applets for interactive content such as online games.

Java is a programming language originally developed by Sun Microsystems (now Oracle). Information on security and stability issues affecting Java is available at Oracle's Critical Patch Updates and Security Alerts page. Plug-ins can cause crashes and hangs and may contain security vulnerabilities. Mozilla applications are regularly updated for security and stability however, Mozilla does not provide updates for plug-ins.
