Not exactly a bug, but a loss of a feature.

The profile used to display the signature. I used it as a quick way to access the links in my signature.

Now, I either have to go into the signature manager (extra clicks) or find a message I posted (even more clicks).

Also unable to make any changes or read any content in Profile in Safari, NetNewsWire, MacFox, and an older Opera.

But I can in Camino.
