I totally understand your frustration — this seems to be an issue with Amazon trying to force passkey login, even if you never set one up.

Here’s what worked for me:

Disable passkeys in Firefox:

• Open Firefox and type about:config in the address bar

• Search for: security.webauth.webauthn

• Double-click it to set it to false

• Restart Firefox

That disables passkey support so Amazon should fall back to the regular password login.

Thank You. That worked very well.

In my frustration, I have to admit....I did try the microsoft browser and came up with the same problem, showing that, as you say, this is an Amazon issue and I deeply appreciate the support from Mozilla, and the ability to choose solutions like this from experts like you. Thank you, again
