Hotmail in N4 and Moz 1.1.
Note the Quick Address List button on the right, and the Attachments down left. These are gone in Moz. You get no attachment option, and you get your full address list instead the Quick option.
It's the same in Moz 0.9, 1.0, and 1.1.
Netscape 6.01 and 7, built on Moz, match N4.
Why? That's pretty specific targeting of Moz if the new Netscapes don't do it.
Update! Since I took those shots, the Attachment button now appears in Moz, but there's still no Quick Address option.
