We'll create fresh WordPress site with Auto Prefetch URL in Viewport installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Auto Prefetch URL in Viewport is an ultra-lightweight javascript plugin (<1 KB) that will automatically prefetch all links(URLs) in the viewport and make your website page load faster like a rocket. It will be supported and maintained until at least 2022, or as long as is necessary.
Once activated, it will embed a small javascript file(auto-prefetch-url-in-viewport.min.js) on your website. There is no other configuration, the auto prefetch URL in viewport settings screens are enabled or disabled by either enabling or disabling this plugin.
