The Java Plug-in software is not a standalone program and cannot be installed separately. Java SE Runtime Environment 7 enables support for running Java-powered applets and applications. This release includes fully supported JRE for Mac OS X 10.7.3 (Lion) and above. Yesterday I updated Java to 'Version 8 Update 131 (build 1.8.0131-b11)', and I can longer use Java plugins on any version of Firefox, which means I can no longer access the VPN. It was my understanding that The ESR versions of Firefox would continue to support Java.

Safari no longer supports most web plug-ins. To load webpages more quickly, save energy, and strengthen security, Safari is optimized for content that uses the HTML5 web standard, which doesn't require a plug-in. To enhance and customize your browsing experience, use Safari extensions instead of web plug-ins.
