In Denmark we have a common Authorization system, called MitID. It has worked fine in Firefox until the last update. But no longer. MitID works fine in Safari, Edge and Chrome. But no longer in Firefox. Since MitID is use for banking and financial services, libraries and all communication with any public service, it is crucial for any Danish user. So unless you will say goodbye to all Danish users - including mee (after many years), you had better correct your bug. Kind Regards
