Microsoft is experimenting with a new feature in Microsoft Edge called “Super Duper Secure Mode” The feature works by turning off something called Just-In-Time (JIT) compilation in the browser’s Javascript engine. JIT is used to speed up browser performance by taking JavaScript and compiling it into machine code before its needed. In 2019, roughly 45% of common vulnerabilities and exposures were related to JIT, Microsoft Edge Vulnerability Research Lead Johnathan Norman writes. You can try enabling the feature if you’re running a beta version of Edge.”]
