The 64-bit version of the Firefox browser does not support NPAPI plugins, including Java plugins. Firefox 52 and newer versions
Starting with the Firefox 52 version (released in March 2017), support for plugins has been limited to the Adobe Flash plugin and the NPAPI standard has been discontinued, which affects Java, Silverlight and other plugins based on NPAPI.
If you experience problems accessing Java applications using the Firefox browser, Oracle recommends using Internet Explorer (Windows) or Safari (Mac OS X). Software developers and system administrators looking for alternative ways to support Firefox users should look at this blog and read the Launching Web Start applications thread.
you should download the older version of firefox from the ftp site or another source, eg firefox 10.0.10esr and older version of java from oldapps page np.java 7 update 6 from 2012 new versions firefox do not have support for java the same applies to Ubuntu, in Ubuntu it is best to install the plugin iced-tea-plugin using the program synaptic, chat on wp uses the older java version which does not start on current browsers
