After a long trial-and-error approach, I got IcedTea working consistently in an older version of firefox like this: Beginning in Firefox version 52, support for NPAPI plugins (java applets) in Firefox has ended, due to performance and security issues, the way that I manage to run java applets is to install the Extended Support Release (ESR) of firefox.

This is an old thread, but I stumbled upon it while googling a solution to my problem today.
