How to Turn on Super Duper Secure Mode in Edge – Guide

There is an old joke among Windows users: “Internet Explorer is the best browser, download a better browser”. In others words, Internet Explorer, Microsoft’s old Internet browser, has been around for years, and few people really like it. That’s a big reason why Microsoft released Edge in 2015, its new and improved browser. Microsoft has put a lot of effort into improving the browsing experience with Edge and it has paid off. Microsoft Edge has enough features and benefits to really be a viable alternative to more popular browsers like Chrome or Firefox. First of all, “Super Duper Secure Mode” is not the official name of this feature. It is still in the testing phase and can be renamed. However, that was the name of the feature flag and it seems to be an internal codename that Microsoft engineers still use, so let’s call it that too. But what does he really do? The Microsoft security team found that the V8 JavaScript engine is responsible for many security vulnerabilities. The JavaScript engine uses “Just-In-Time Compilation” (JIT) to speed up up JavaScript code in web pages, but it opens some vulnerabilities in the browser. JIT exists to accelerate up your browsing, but Microsoft says turning it off doesn’t always have a negative impact on performance. Super Duper Secure Mode also activates Control-flow Enforcement Technology (CET), a hardware-based exploit prevention tool from Intel, which also crashes the browser.
