I'm trying to switch to OS X from Windows and there's a few things I can't figure out how to do. One really simple thing, how do I launch a new window for an app without opening an existing window for that app? I'm thinking especially here for Firefox or a browser. I may have a number of browser windows minimized on the dock, but I need a brand new window to browse something else. On Windows, when you click the firefox icon, you get a new firefox window. Seems sensible. On Mac, I get one of the old Firefox windows - not what I really wanted. Obviously I can do that, and hit Apple-N, or something, but is there an easier way?
