Not sure if this is what you are experiencing, this was taken from Java 

/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.//

          Firefox 52 ESR 32-bit release


Mozilla offers an Extended Support Release (ESR) 
<https://www.mozilla.org/firefox/organizations/> version of Firefox 
specifically for use by organizations who need extended support for mass 
deployments. Only Mozilla Firefox 52 ESR 32-bit release will continue 
offering support for the standards-based plugin support technology 
required to launch Java Applets. To see if you are using an ESR release, 
check the Firefox menu item (Help -> About) and looking for the "ESR" 

Mozilla maintains Firefox ESR Releases for approximately one year. 
Developers and users still relying on the Java plugin technology in the 
32-bit Mozilla Firefox web browser should consider migrating to a 
different solution. *


Even with 'ESR', it appears the writing is on the wall for Firefox with 
regards to Java.
