I don’t really understand why removing the bottom status bar is a problem for you. Firefox will still display where hovered links are pointing to. (I would argue that displaying that information in the address bar is a great solution that’s much easier to understand.)
I also don’t understand why you have a problem with turning the RSS button into a toolbar button that’s not on the default toolbar.
And I don’t understand how you go from that to the conclusion that removing features is always a bad idea.
I really like that the status bar has moved to the address bar. The extra screen space is great. I still have Firefox 3 on my laptop and it feels like there is too much in the way now.
I even like that the menu bar has been rolled up into the Firefox button. There is no reason to display those menus all of the time.
