Might be because of their redirection shenanigans, starting yesterday apple.com was a 301 (permanent redirect) to apple.com/live, might sudden changes back and fro be interpreted as phishing attacks?

Firefox is saying the same thing for me. In fact, I thought that was the point of the link (to show apple.com is marked as a phishing attempt).

And just like that, now it is magically fixed.

Yup, me too!
