I like to browse the web using Safari while working in my Mac, but there is something I do not like about it. I do not like when I click in a link, it to open in a new window. I want it to open in a new tab.
Fortunately, there is a way to change this Safari's default behaviour.
Make Safari, open link in new tab
Safari -> Preferences.
Click on the "Tabs" tab, and change:
Open pages in tabs instead of windows: from, Never to Automatically.
