[Mozilla Enterprise] Message CORS request failed on Firefox 68 ESR

[Michel BOISIS]

Hello,

our company is developing full web software for municipal libraries.

Our application works in HTTPS but must access an RFID plate via a web 
service which works in HTTP only.

With Firefox 45 ESR, it worked fine.

With Firefox 68 ESR we get the following message when connecting from 
our application to the web service of the deck in HTTP:

Platinum config init: RfidNedap: Rfid Config => proxyService: 
urlService: http: //localhost/nedaprfidwebservice.asmx cnx chain: 
192.168.4.71 formatTag: 513 rfid-4.1.26.js: 23: 11
Blocking of a multi-origin request (Cross-Origin Request): the "Same 
Origin" policy does not allow consulting the remote resource located on 
http: //localhost/nedaprfidwebservice.asmx. Reason: CORS request failed.

Is there a way in Firefox ESR 68 to allow this connection over HTTP?

For information, the request does not also work on Firefox 68.0 but 
works correctly on Firefox 72.0.

Why doesn't it work in Firefox 68?

Have a good day

Michel Boisis
