Quite a good idea but seems dependent on a connection to the getpersonas website for content: as of writing the website is down and suddenly my personas skin stops - I can barely read the text in my toolbars (white on white) and had to revert to the default persona (pale blue - maybe the default firefox skin).
You don't get that with a regualar skin - you're not dependent on some external website for it to work.
Why doesn't Personas store the data locally? Is it collecting data (IP address etc) every time Firefox fires up?
Not comfortable using it now and will revert to a regualr skin.
