This si really going to depend on the browser you are using. You can set the link to open in a new window using the old target=”_blank” syntax. Way back this would launch a new browser window. Eventually browsers made it so instead of a new window, it was a new tab (thanks firefox). Then the browsers used configs that even if the website didn’t specify to open in a new window, you can make it that any external link of the site was a new tab (either foreground or background).
So bottom line is that it will depend on the user itself. All you can do is suggest a link open in a new browser/tab.
