The good:
They finally removed the old Phoenix throbber and replaced it with something more generic, but I would like to see a small Firefox throbber that flashes slowly when a page is loading in. Wishful thinking, I know, but the Firefox logo is very colorful, and it would make for a nice splash of color to the browser UI.
The other positive thing is the existence of a Mail button, but it would seem that to get the true intent of it, Thunderbird would have to be installed as well, and also set as the default mail client in Windows. When I clicked that button, it loaded Outhouse Express 6.
The negative aspect I have found in 0.9 is when secure pages are loaded. In Mozilla, clicking the yellow lock icon brings up a window which displays information about the web site, as well as secure certificate information and the encryption of the connection. In Firefox 0.9, none of this occurs aside from basic page information, no security information at all. This really defeats the purpose of the yellow icon. Moving the mouse over it only indicates which certificate authority issued the certificate for the web site.
Just my .10, adjusted for inflation.
