Enabling the Back/Forward Cache (bfcache) For Your Magento Store

The Problem
Magento Disables
Back/Forward Cache

All major browsers, Chrome, Firefox and also Safari, have a so called Back/Forward Cache (bfcache).
The idea with this cache is to provide instant page loads when a user navigates a website via back and forward buttons.
These instant page loads are achieved by caching a page viewed by a user and returning this cached version without any network request - even better: It is a complete snapshot of the page, including the JavaScript heap and other than e. g. the browsers HTTP cache, the bfcache is an in-memory cache, which allows ultra-fast response times!
A tiny little feature that makes a huge difference not only for Core Web Vitals (CWV) but directly boost the user experience dramatically!
An awesome user experience you definitely want your customers to enjoy, right?
But bummer, the problem is, by default Magento tells the browser to not use the bfcache!!!
Yes, you read this right, Magento disables this amazing and game changing performance feature at least for any customer browsing your store using Chrome or Firefox.
Bit no worries, your customers no longer have to use your site without bfcache...
Read on to learn more about our Back/Forward Cache extension to speed up the browsing experience and at the same time improve your CWV field data significantly in your Magento 2 store.

How Back/Forward Cache (bfcache) by JaJuMa
Improves Your Magento Store

Improved Page Load Times:

Instant Page Loads!
Yes, you read that right. With bfache, back/forward navigation's will restore the rendered page from in-memory cache. No network request, no reading from disk - literally the fastest possible page loads!

Smoother Browsing Experience:

While searching for the right products, your customers frequently go back and forth using the browsers back/forward buttons.
With bfcache enabled, your customers will experience and love the instant page loads and responsiveness of your site without any delays, waiting times and page rendering.

Improved Core Web Vitals (CWV) Field Data

Core Web Vitals where designed for measuring the User Experience. So of course, instant page loads via bfcache have a direct positive impact on your Core Web Vitals!
Thanks to bfcache being able to restore the rendered state of a page, without needing to load any resources from server, Content Layout Shift (CLS) will literally be 0 and your Largest Contentful Paint (LCP) be as fast as it can get.

Reduced Server Load

bfcache will save you server resources!
Pages restored from bfcache are displayed to your customer without any server request.
This means, by enabling the bfcache you can reduce server load noticeably since back/forward navigation's don't need to be processed anymore by your server.

Back/Forward Cache (bfcache) - A Performance Game Changer In Action...

"The bfcache is a significant browser-level performance optimization, and it entirely eliminates the layout shifts during page load, which for many sites is where most of their CLS occurs. The introduction of the bfcache caused the biggest improvement in CLS that we saw in 2022."
(Source: Top Core Web Vitals recommendations for 2023 by Chrome Developer Relations Team)

The chart from HTTP Archives Technology Report visualizes why Google Developer Relations Team sees bfcache as a significant browser-level performance optimization that caused the biggest improvement in CLS in 2022.

Each line in the chart represents the percentage of sites using a certain technology that passes the Core Web Vitals test. Sites using bfcache (e. g. Lightspeed eComm, Shopify, Shopware & OpenCart) saw a huge bump of sites passing CWV between December 21 and January 22, while other technologies remain stagnant (e. g. Magento & BigCommerce). The later because these technology's / cart systems do not use bfcache.

It is time for your Magento store to get the same performance bump from bfcache as your competitors, right?
