I don't know if this applies to anybody else as well, but before installing Firefox 3, I had moved the location bar to the same toolbar as the menus and hidden the Navigation Toolbar. Having now installed Firefox 3, when I unhide the Navigation Toolbar, another location bar is there, and that one responds to Ctrl + L and Alt + D, and it functions as expected. I have since reverted to the original layout of Firefox, as it is the only way to resolve the problems, as I am experiencing them, at the moment.
