Speculative Navigation
Experimental
Google's Speculation Navigation Rules API
"Prefetching or even prerendering certain URL's for a (almost) instant page loading experience."
Imporant!
Make sure you (temporarily) turn off any content blocking tools like uBlock Origin or AdBlocker like web browser extensions. Otherwise the prefetching will not work.
