Greetings from Greece, i use Mozilla Fieefox many years now to sync everything from home, to mobile and work. Today at work, I received a new computer with fresh Windows 11 installation, bind to an MS Domain and the latest version of Firefox installed. With a great dissapointment i realised that i couldn't connect with my mozilla account while in the previous pc with with windows 10, worked and synced flawlesly. While pressing "Sign In" from the 3-line menu on the top right corner nothing happens, sometimes it opens a window that keeps loading and some times the login page is loaded. After inserting the email and pressing the button it takes quite some time, a red ribbon notification appears "Proccessing..." and when next screen appears and the password is entered... (it takes also quite some time) the red ribbon notification appears "Working..." and after a little while "The operation was aborted". I've uninstalled and reinstalled firefox, cleared profiles and created new ones, took advantage of all refresh tools mozilla offers.... nothing. In fact in all 3 pc's we received today the reaction was identical. On the other hand if i try to login to mozilla throught Chrome or Edge the login process works like a charm. Any thoughts, ideas would be very much appreciated.. could it be a Policy Problem for Windows 11 for example?!? Thanks in advance for your time
