Some popular sites such as Youtube and Facebook will have it disabled for now. Our plan is to provide users control over which sites run without SDSM but we however need to implement the logic and effigy out a good default.

Norman notes that some sites, such every bit YouTube and Facebook, disable Super Duper Secure Style. Microsoft plans to let people choice which sites use the feature in the hereafter.

Super Duper Secure Mode works by disabling the "Just-in-Time-Compilation" (JIT) engine. Using the JIT engine tin ameliorate the performance of websites, but it comes at the price of security.

"Operation and complication often come at a cost, and often we behave this cost in the course of security bugs and subsequent patches," explains Microsoft. "Looking at CVE (Common Vulnerabilities and Exposures) data afterward 2022 shows that roughly 45% of CVEs issued for V8 were related to the JIT engine."

Microsoft constitute that disabling the JIT engine can reduce vulnerabilities. Super Duper Secure Manner is all the same in its early on testing phases. Microsoft explains that it will likely change to something "more professional" in the future.
