hello, I use SAS University Edition to learn how to improve my SAS knowledge. It's installed via a VM and once installed, you just have to type http://http://localhost:10080/ in the browser to open the SAS session. It worked for months, until new releases of Firefox. I disabled the HTTPS only mode on Firefox. Now I get a Firefox error message "Cette adresse est interdite - Cette adresse utilise un port réseau inhabituel pour la navigation web. Par mesure de sécurité, Firefox a abandonné la requête." Forbidden address, due to unusual network port usage. How can I log on my virtual machine? Where are the parameters that restrict the access to http sites and how can I manage them? Thank you for your help, PY
