Hookpad - login problems, Firefox 96.0.2

System: Intel-Mac, Catalina, Firefox.
Since yesterday (25.January 2022) the “busy”-circle would turn forever, login wouldn’t happen. Might have been an issue with the 20.January - update from Firefox.
Safari works.

edit: In Safari it works but I don’t hear anything - no sound at all. very strange (no: its nothing wrong with the computer nor Safari, tested…)
