In most OS X Apps (Mail, IE, Office v.X, Yahoo Messenger, etc), if you have minimized a window and have no other windows active, when you click on the Dock icon for that app, the most recently minimized window is maximized (opened). Mozilla does not do this. From Apple Aqua Human Interface Guidelines -> The Dock -> Clicking in the Dock "When a user clicks an open application's icon in the Dock, the application becomes active and all open unminimized windows are brought to the front; minimized document windows remain in the Dock. *** If there are no unminimized windows when the user clicks the Dock icon, the last minimized window should be expanded and made active. *** If no documents are open, the application should open a new window. (If your application is not document based, display the application's main window.)"
