However, Mozilla offers an “Extended Support Release”, or ESR, branch Mozilla ended support for traditional NPAPI browser plugins, asideįrom Flash, with Firefox 52 on March 7, 2017. There is a special version of Firefox that still supports NPAPI plugins. Here's a list of browsers that still support NPAPI from Wikipedia: IcedTea, then remove them: sudo apt-get remove icedtea-plugin icedtea-8-plugin icedtea-netx icedtea-netx-common If it doesn't work and the wrong Java plugin appears to be loaded eg. Launch Firefox and verify your Java version here: Verify Java Version Ln -sf $PWD/lib/i386/libnpjp2.so ~/.mozilla/plugins/ Now the Java needs to be linked to Firefox.

Download and extract the Firefox ESR install from here: Download Firefox Extended Support Release.The following steps should work (tested on Mint 18 based on Ubuntu 16.04 and Mint 19 based on Ubuntu 18.04): There may be other ways to activate Java plugin in Firefox ESR, but this way really works.You can use the Extended Support Release of Firefox 52 as follows: To activate this plugin at Firefox ESR, you must create a symlink to the folder where is installed your Oracle Java: mkdir /firefox/browser/plugins I consider this as the best practice for Firefox, because OpenJDK will not install libnpjp2.so, essential to activate Java in Firefox ESR. In this case, Openjdk plugin didn't work with Firefox ESR, but Oracle Java, installed as followed from Digital Ocean tutorial.Īlthough they told that it's deprecated (because it applies to Ubuntu 12.04), the procedures are the same: you can use it in ubuntu 17.10, just downloading jdk 8u161. In fact, this solution doesn't depends on which kind of java is installed and operating in this system. Right-click on Name title, choose New Preference > BooleanĬreate a new entry with this label: plugin.load_flash_only Open your browser and type this: about:config

Not clear why firefox has trouble using installed java. Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode) I am able to run java successfully through command line $ java -version The java command is a symlink to /etc/alternatives/java which is a symlink to /usr/lib/jvm/java-8-oracle/jre/bin/java I get this exception in the terminal from which firefox was startedĮxception in thread "main" Īt .JVMManager.getOrCreateBestJVMInstance(UnknownĪt .JVMManager.startAppletImpl(Unknown Source)Īt .JVMManager.startApplet(Unknown Source)Īt .MozillaPlugin.maybeStartApplet(Unknown Source)Īt .tWindow(Unknown Source) With these changes, when I startup firefox and go the Īnd click on the link Firefox 52 ESR users: If you'd like to run the verify app as a plugin, please click here. Is a symlink pointing to /usr/lib/jvm/java-8-oracle. Made sure Oracle's java is the default java. $ ln -s /usr/lib/jvm/java-8-oracle/jre/lib/amd64/libnpjp2.so.
