Apologize the noise. Just for the record:

Firefox limits NPAPI support (technology required for Java applets)

64-bit Firefox

The 64-bit version of Firefox does not support NPAPI plug-ins, including

Java.

Firefox 52 and above

Beginning with Firefox 52 (released March 2017), plug-in support is
limited to Adobe Flash, and drops support for NPAPI, impacting plugins
for Java, Silverlight, and other similar NPAPI based plugins.
