The Disappearing Forms
A common and highly frustrating occurrence in Google Chrome is losing data when navigating backward. Imagine spending ten minutes filling out a complex online form. You click a link to read the Terms of Service, which opens in the same tab. When you hit the “Back” button to return to your form, Chrome automatically forces the page to reload from the server. The page refreshes, the fields wipe clean, and all your entered data is lost. This happens because the browser’s cache management decides the page data is stale and must be fetched again, rather than instantly loading the exact visual state you left behind from memory.
Enabling the Back-Forward Cache (bfcache)
To stop Google Chrome from automatically reloading web pages every time you click the back button, you can force the browser to utilize its Back-Forward Cache (bfcache) more aggressively via experimental flags.
Open a new tab in Google Chrome. In the address bar (Omnibox), type exactly chrome://flags and press Enter. This opens the experimental features page. At the top of this page, there is a search box. Type back-forward cache into the search box. You will see a result labeled precisely “Back-forward cache” (which caches entire pages in memory when navigating backward and forward). Click the drop-down menu next to this flag, which is likely set to “Default.” Change the setting to Enabled. Chrome will prompt you to relaunch the browser with a button at the bottom of the screen. Click Relaunch. Once Chrome restarts, it will prioritize saving the exact state of the page (including filled-in form fields) in your RAM. When you click the back button, the page will instantly visually restore without automatically triggering a server reload.
