login.live.com for Microsoft has a peculiar login-form

[TimvanSteenbergen]

One screen only having uid-field, then next screen has the password-field. Opfes behaves strange.

[TimvanSteenbergen]

On the first screen, login gets prefilled with the userid in the userData, is ok. But the Opfes-password-field gets shown, although there is no visible password-field. Should not happen. Also, clicking Next forgets the prefilled userid. And in the second screen, after filling the password, even when it is the correct one, it gets denied. Shutting down Opfes, refresh, fill correct userid and same password: login succeeds.
Solved when:

• login-field gets prefilled with the userid in the userData.
• opfes-password-field only gets shown on the page having a visible password-field.
• login succeeds while Opfes is active.
