Backward Forward Cache

back/forward cache to cache pages in memory (preserving JavaScript & DOM state) when the user navigates away.

A back/forward cache (bfcache) caches whole pages (including the JavaScript heap) when navigating away from a page so that the full state of the page can be restored when the user navigates back. Think of it as pausing a page when you leave it and playing it when you return.

At the moment 19% of all navigations on Android and 10% on the desktop are back-forward.
