No, this is not a FF problem.

If you download the jnlp file into a temp dir, then try to open via line command, you get the same problem

[lesca@dodo ~]$ wget -q jws.agenziaentrate.it/jws/dichiarazioni/2018/FEL18.jnlp -O /tmp/FEL18.jnlp
[lesca@dodo ~]$ javaws.itweb /tmp/FEL18.jnlp # (wait 10/15 munutes)

Only if you use the javaws.itweb "-noupdate" option all work fine ...

so who is this problem?
