Activate One Window mode for Safari.

If you’re like me, you’re tired of all sorts of Safari windows all over the place, and wish you could keep them all in one browser window! If that’s the case then you’ll love this terminal trick that does just that for Safari, here’s what you do. Browse to terminal ( applications/utilities/terminal.app ) and enter the following command:

defaults write com.apple.Safari TargetedClicksCreateTabs -bool true

You’ll have to restart Safari for it take effect, but now any links that are set to open in a new window will now open in a new tab saving you from having 10 browser windows open all the time.Of course to reverse this setting, you simply enter the same command except change ” true ” to false at the end.
