Why isn't this configurable, so I can choose whether the right mouse click opens in the current tab or a new one by default?
That, and FireFox's "awesome bar" (stupid name for a great feature) is why I don't use Safari on a day-to-day basis...
That is a very specific thing to configure - whether "right-click select search in google" opens a new tab? Then do you want another setting for "search in spotlight?" Should everything have its own setting?
