Microsoft Edge is getting a new security feature known as “Super Duper Secure Mode,” and you can try it now with the latest Canary build of the browser.

According to the company, bugs in JavaScript are among the most common ways that attackers exploit. The technology is called JIT (Just-in-Time), and it’s meant to render sites faster, but it can also lead to security exploits. The Super Duper Secure Mode in Microsoft Edge improves browsing security by turning off the JIT (Just-in-Time) JavaScript engine and enabling additional security mitigations. Of course, disabling the technology will impact performance, but in the real world, it’s unlike that most people will see a significant difference.

The Super Duper Secure Mode is still a work in progress, and Microsoft has to figure out some challenges before making it available to everyone. Furthermore, the company is planning to integrate this mode so that the browser is smart enough to detect the site and enable or disable the security feature automatically. However, until then, you can enable the Super Duper Secure Mode from the experimental settings page.

In this guide, you will learn the steps to enable and try the new security feature on Microsoft Edge for Windows 11, Windows 10, and other platforms.
