How to Enable Super Duper Secure Mode in Edge – Guide
We first heard about the Super Duper Secure mode in August when Microsoft started experimenting with feature in beta channels. I’ts very interesting feature which goes against common practice – it basically disables the JavaScript V8 engine speed-enhancing JIT compiler in your Edge browser. I know this whole “JIT compiler” thing sounds like mumbo jumbo, so here’s a pretty basic explanation. The JIT compiler is a 12 year old tool that increases JavaScript performance at the expense of security (to reduce web page load time). Nearly 45% of JavaScript V8 vulnerabilities are JIT related, and many of the browser updates you need to install are just patches for those vulnerabilities. I suggest keeping the Balanced mode, which tells Edge to trust your most visited sites (to ensure they load quickly). Strict mode is much more persistent, and even Microsoft warns that it will break parts of some sites. If you like to get your hands dirty, you can also add some exceptions to the Super Duper Secure tool. This can be useful when the Super Duper Secure mode slows down or interrupts the main sites you visit, eg B. Your work or school sites. JavaScript engines are “a remarkably difficult security challenge for browsers,” Norman explained, in part due to their use of Just-In-Time (JIT) compilation, also known as speculative optimization.
