Personas, skins, well it just looks plain daft to me and selected a few and then could not read the buttons properly with some of them and I don't see anything there for me at the moment. I just found them too distracting from what I have been used to with the browser. And with recent releases of FF I am firmly in the camp that less is more. FF 3.6 seems to be more stable and less prone to lock ups - but I have 3 tabs open and am using 231,456K of memory - which doesn't decrease as I close tabs. Doesn't seem right to me.
