Cannot Login to Home Assistant Community in Firefox Desktop

Hi all,
I’ve the strangest of problem. I’m registered on this plaform using my NABU casa account and I can login correctly from mobile (tested firefox and chrome) but from desktop I can only login in chrome. If I enter my credential in firefox I get “Could not retrieve your user details. Do you have an active account?” error.
I’ve alredy tried doing it in incognito mode and empting the cache and also from another PC with a new installation of the OS and firefox (neven opened before) and still get this error.

Anyone as any idea of what could be and how to debug?

Thanks in advance.

I read the post but sorry I don’t really understand the problem. I always logged in using the middle button (use home assistant Cloud account) and still works in every browser that is not Firefox desktop. Am I missing something obvious?
