I use the flickr website many times during the day without issue, unti now. When trying to login this time I get the message shown in the attached image. I have gone through all the usual procedures, clearing cookies etc, including starting Firefox in safe mode, but still the problem persists and I am now at a loss. As a test, I even installed the Chrome browser and I was able to log into flickr with no problem. I have a laptop running Window 11 and the latest Firefox and the problem is the same on that - no flickr login.

Thank you for your help
