If the Java plugin doesn't show in Tools Add-ons Plugins then Firefox doesn't find this plugin. If it does show, but is disabled then you can enable the Java plugin. Note that the security block of the Java plugin has been lifted, so it isn't blocked anymore once the blocklist file has been updated. Download Mozilla Firefox, a free Web browser.

The current Firefox 52.1.1 esr version should still support the Java plugin AFAIK. Make sure that you have the Java plugin present in the correct location in case the Java updater didn't do this properly.

Up until yesterday I've been using Firefox ESR 52.1.0 (64-bit) in order to access a VPN I need for work, which requires a Java plugin. I'm also running Firefox Developer Edition 54.0a2 (2017-04-20) (64-bit).Yesterday I updated Java to 'Version 8 Update 131 (build 1.8.0_131-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 through into 2018, but this has not been my experience.

Are there any specific issues with these versions of Firefox that prevent Java Plugins from working, or is this an issue with that version of Java itself?

Thanks!

Beginning in Firefox version 52 released March 7, 2017, installed NPAPI plugins are no longer supported in Firefox, except for Adobe Flash Player. Some of the plugins that no longer load in Firefox, even though they may be installed on your computer, include Java, Microsoft Silverlight and Adobe Acrobat. See this compatibility document for details.

Over the past few years, Firefox has implemented various Web APIs so that websites can do the same things they’ve always done without plugins, so you will most likely not notice any change to your browsing experience.

The internet is full of websites that go beyond static pages, such as video, sound and games. While NPAPI plugins, especially Flash, have helped enable these interactive pages, they also make your browsing slower, less secure and more likely to crash.

Over the past few years, Firefox has worked hard to build replacements for these plugins, these replacements are called Web APIs. Web APIs are designed to replace the function of the NPAPI plugins without undermining your internet security, stability and performance.

Before, while these Web APIs weren’t quite ready, Firefox started to transition by making plugins load manually (click to activate).

Now, many sites have adopted Web APIs, and almost all your favorite pages can be enjoyed without using old and insecure plugins. Firefox joins other modern browsers like Google Chrome and Microsoft Edge by removing support for these NPAPI plugins.

We recommend that you update Firefox if you can.
