I know the way macs zoom is different (and subjective relative to windows) and everyone has their preferances. I actually the mac idea - windows only as large as needed. What's annoying is that non-Apple apps don't implement zoom/maximise as it should be in mac OS. The inconsistency of the green button depending on the application is really infuriating! Is there anyway to make OSX firefox zoom/maximise like it should on mac OS (zoom the window to the size of the contents)?
