That isn't a FF doing that is the site doing format if it comes with the newer MS extension then that is what it is. If you having problems from that site then you need to contact them about it.

I assume you mean JDK on the server sending HTML/JavaScript/CSS to Firefox, and not a Java plugin applet (which no longer runs after Firefox 52 Extended Support Release).

Do you know what content-type header the web app is sending for XLSX files? I think these are preferred:

  • XLS: "application/vnd.ms-excel"
  • XLSX: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"
