Microsoft recently rolled out an update to the stable version of its Edge browser. The update brings Edge to version 96.0.1054.29 and includes several new features. Microsoft outlined most of these improvements in achangelog, but that page does not list the addition of Super Duper Secure Mode support. The quiet rollout of that feature was confirmed by Microsoft Edge Vulnerability Research Lead Jonathan Norman.
Super Duper Secure Mode disables the “Just-in-Time-Compilation” (JIT) engine to improve security when browsing. The JIT engine can improve the performance of websites, but those improvements may come at the cost of security. Normanexplains Super Duper Secure Modein more technical detail.
The mode has two different options; balanced and strict. The balanced option adds security mitigations for sites people don’t visit as often. When switched to balanced, Super Duper Secure Mode shouldn’t affect the performance of most websites. The strict setting adds security mitigations for all sites. The drawback is that this option can prevent parts of certain websites from working.
We quietly released Super Duper Secure Mode to stable (96.0.1054.29). Users can now toggle between Balanced and Strict modes. Balanced learns what sites you use often and trusts those, strict is well.. strict :) Users can now add their own exceptions.
