You have to change settings in your admin page. Please go to Download->Settings and find out the Open in Browser checkbox and check the box and than Save Settings. Now it should open the file in new tab.
Thanks, but this opens the file in the current tab and not a new one and thus navigating a user away from the site.
Thanks,
