firefox esr doesn't resolve local address

Firefox Fehlerbehebung

I successfully downgraded from FF 70 to FF esr 68 in my soho. Alas, I the esr version doesn't resolve the address of my office server, whereas FF70 does it and so does chrome. When I try something like http://myserver.myhome.xx:myPort , FF esr responds with an error page "The requested URL could not be retrieved". I can use the local IP as a workaround but that is not what I am looking at. Is there a setting that makes FF esr resolve local addresses?
