Unable to sign in to Microsoft account with Firefox
I am unable to sign in to the Microsoft Forum using Firefox. Edge works fine. I get a message about my account not existing (anonymised):
Sorry, but we’re having trouble with signing you in.
AADSTS50020: User account '******@yahoo.***' from identity provider 'live.com' does not exist in tenant 'Microsoft Services' and cannot access the application '99adaf47-f643-4c0e-8117-15335c87ebda'(Microsoft Community) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account.
Troubleshooting details
If you contact your administrator, send this info to them.
