Seems like whenever I connect to my Apple account on my Mac with Firefox I get a "Your Apple ID is being used to sign in to a new device", I'm offered a numeric code I need to type in on the same device (duh?), and hit TRUST. I just downloaded a photo from iCloud, and needed to do this, and then I went straight to another Apple site and it made me do it again. This is NOT A NEW DEVICE. I use it ALL THE TIME. Once I do this validation, what is making my device suddenly untrustworthy? Absolutely bizarre.
