Chrome’s back-forward cache feature is coming to desktops

Google announced a long-awaited feature for its Chrome browser last week: the ability to save the previous page state—including content, images, typing, and other details—and restore it later. The feature, called “back-forward cache,” was first unveiled last year as a Chrome Labs experiment, but was never made available to the general public. Now, Google is saying it will be making the feature available by default in Chrome 62.

Google announced it’s coming to desktops with Chrome 49, a new feature that will allow users to “cache” back-forward history, and thus reduce the need to re-visit old sites. The theory is that users will be able to go back to the sites they visit often, and then will find it easier to recall what they did on those sites. This feature may have a little impact on usability for some users, but will have a larger impact on Chrome users.

Over the last few years, most of the web’s biggest companies have been slowly rolling out the ability to save your favorite webpages in a custom, back-forward cache that is stored on your desktop. This is a great feature, because it allows you to browse a page while offline, or even while on a plane, without having to load the page from scratch.

  • Google is currently attempting to bring an Android browser functionality to the Chrome browser on computers.
  • Microsoft has announced that it is developing improved code caching for scripts retrieved over the chrome:/ protocol.
  • Some users will be able to use the back-forward cache capability for desktop with Chrome 92.
  • Although no release date has been set, a bigger rollout is likely later this year.


It’s been a while since we discussed one of the most popular browsers on the market. We’re back with some news that will no doubt please Google Chrome users.

On Windows, Linux, macOS, and other desktop platforms, the Redmond tech corporation is now working on a new feature for Chrome that will increase the pace of internal pages.

These improvements to the cache will speed up browsing.

So, let’s continue by explaining that this functionality makes advantage of caching to enable immediate page loading when users go between internal browser pages (chrome:/), such as the new tab page.

Through a new Chromium code commit, Microsoft announced that it is working on a new code caching functionality for scripts downloaded over the chrome:/ protocol.

V8 can serialize the interpreter bytecode generated for a script after it has been loaded and executed. If Blink later notifies V8 to run the same script and gives the previously serialized bytecode, V8 can bypass the initial parsing phase and the script will run faster. This is significant in terms of page load time.

As you may be aware, Chromium-based browsers such as Chrome include huge scripts in WebUI pages, which are used in several popular instances like the new tab page.

As a result of using a prototype version of a new feature, the tech giant saw an 11-20 percent reduction in time to first contentful paint on the new tab page.

–enable-features=WebUICodeCache can be used to enable the feature, which is currently disabled by default. The configuration for a field trial will be added in a later release.

Because many WebUI data sources currently refuse to use the network cache, response time is no longer a reliable indicator of whether the script’s content has changed.

Furthermore, any data from the bytecode cache is always rejected by this response time comparison.


Another thing to keep in mind is that Google is working on an update to their web browser that will dramatically enhance the speed with which web pages load.

Back-forward cache on desktop is a long-awaited new feature that will be available to select users with Google Chrome 92.

This feature has been present on Android for a long time, if you didn’t know. When users click the back or forward buttons, it allows them to load sites almost instantly.

When a user navigates away and returns to the same page via session history navigation, the above-mentioned feature tries to keep the page alive.

Google has been testing this feature for the past two years, and it has now reached the experimental level, with some users receiving it in Chrome 92.

A release date has yet to be determined, according to a Google group discussion. However, later this year, a broader deployment is planned to commence.
