Recently, Microsoft introduced a new experimental flag for its Edge browser called "Super-Duper Secure Mode." When enabled, the flag disables JIT in the JavaScript V8 engine to make Edge safer. JIT (just-in-time) is a compiler that preloads JavaScript code before the browser needs it to improve performance and make it feel snappier. According to Microsoft, half of the bugs in the V8 engine have their roots tied to JIT; thus, disabling the technology improves security significantly.

The latest update for Microsoft Edge Canary brings an improved Immersive Reader with more customization options. In version 94.0.981.0, users can adjust text width in Immersive Reader and switch between narrow, medium, and wide column sizes.

Here is another significant change Microsoft made in the latest update to Edge Canary. Previously we covered a new feature that allows you to open favorites folders in tab groups, and now Microsoft brings a new section to Edge's settings.

Microsoft has released a new build of Chromium-based Microsoft Edge 94.0.975.1 for the Dev Channel. It brings several new features as well as various fixes and improvements.

In Microsoft Edge, you can store bookmarks in different folders for improved sorting and convenience. Also, the browser allows opening all favorites in a folder with a single click in a new or current window. In the most recent update to Edge Canary, Microsoft added another option: open favorites in a new tab group.

Microsoft continues improving Performance Mode (recently renamed to Efficiency Mode) with new features and capabilities to let you run the Edge browser as smoothly as possible, even on budget hardware. "Sleeping Tabs" is a cornerstone of Efficiency Mode that allows you to save RAM and CPU resources by putting inactive pages to sleep. In Edge 92 Stable, the browser freezes tabs after no less than 5 minutes of inactivity. In Edge 94, that timeout reduced almost to zero.

Microsoft Edge allows you to enable the Save as PDF context menu command in Microsoft Edge. A new option in settings makes it easy to add or remove it.

In the official blog, the Microsoft Browser Vulnerability Research team details a new flag for Microsoft Edge called "Super-Duper Secure Mode." It intends to improve Edge's security by disabling JIT (Just-in-Time) compilation in the V8 JavaScript engine. Microsoft says bugs in JavaScript inside modern browsers are the most common vector for attackers. According to CVE data from 2019, approximately 45% of attacks on V8 relate to JIT. Disabling that component makes Microsoft Edge more secure and harder to crack. Also, "Super-Duper Secure Mode" includes additional security measures and mitigations.

Microsoft today released the first Chromium 94-based build of Edge in the Dev channel. It is notable for having several new policies, a second row of Top Sites on the New Tab Page, and for a few new features for iOS and Mac. Traditionally, there are fixes and general improvements.

Microsoft has released Edge 93 to Insiders on the Beta channel of the browser. Beta channel builds can be used as your daily driver. They are relatively stable, as the bugs in such builds are all known and minor. Today's release is version 93.0.961.11.
