Microsoft has announced a new tool for its browser that will help users monitor performance and security. “Browser Essentials” is a journal-style dashboard that will eventually replace the existing Performance Hub with its own performance-based tools, such as Efficiency Mode and Sleeping Tabs.
In addition to providing access to existing features, Browser Essentials will provide you with a general browser performance score. This will help you better understand Edge and know if you need to turn certain features on or off, turn off resource hogging tabs, etc.
Another addition to Browser Essentials is Smart Screen reports and scanning results. It will show you how many websites and downloads have been analyzed by SmartScreen, giving you a detailed insight into your browsing security. In addition to your personal security details, Browser Essentials displays general information about security measures in Edge, such as how many malicious websites and downloads it has blocked.

Microsoft plans to expand the new tool based on user feedback, so expect more to appear in future updates. Right now, the browser essential tool is available to all Canary users and about half of DevChannel users. You can access browser accessories using the heart-shaped button on the main toolbar. Like the early changes in Edge, you can tell Microsoft what you think using the thumbs up/down buttons.
