Article03/04/2025 In this article -->These are the latest features in the Stable release of Microsoft Edge DevTools.Use the DevTools in Windows high contrast modeMicrosoft Edge DevTools is now displayed in high-contrast mode when Windows is in high-contrast mode.Follow the instructions to turn on high-contrast mode in Windows. To open DevTools in Microsoft Edge, select F12 or Ctrl+Shift+I. DevTools is displayed in high-contrast mode.Note: DevTools currently supports high-contrast mode on Windows, but not on macOS.Chromium issue #1048378See also:Check for contrast issues with dark theme and light themeMatch keyboard shortcuts in the DevTools to Visual Studio CodeFrom your feedback and the Chromium public issue tracker, the Microsoft Edge DevTools team learned that you wanted to be able to customize keyboard shortcuts in DevTools. In Microsoft Edge 84, you can now match keyboard shortcuts in DevTools to Visual Studio Code, which is just one of the features the team is working on for shortcut customization.To try the experiment:In DevTools, open Settings by pressing ? or clicking the Settings () icon in DevTools.In the Experiments section, select the checkbox Enable custom keyboard shortcuts settings tab (requires reload).Reload DevTools.Open Settings again, and select the Shortcuts section.Click the Match shortcuts from preset dropdown list, select DevTools (Default), and then select Visual Studio Code.The keyboard shortcuts in DevTools now match the shortcuts for equivalent actions in Visual Studio Code.For example, the keyboard shortcut for pausing or continuing running a script in Visual Studio Code is F5. With the DevTools (Default) preset, that same shortcut in DevTools is F8, but with the Visual Studio Code preset, that shortcut is now also F5.The feature is currently available in Microsoft Edge 84 as an experiment, so please share your feedback with the team!Chromium issue #174309See also:Customize keyboard shortcutsRemote debug Surface Duo emulatorsYou can now remotely debug your web content that's running in the Surface Duo emulator using the full power of Microsoft Edge DevTools.With the Surface Duo emulator, you can test how your web

Features available in Microsoft Edge 84 that were contributed to the open source Chromium project.Fix site issues with the new Issues tool in the DevTools DrawerThe new Issues tool in the Drawer (now Quick View panel) at the bottom of DevTools reduces the notification fatigue and clutter of the Console. Currently, the Console is the central place for website developers, libraries, frameworks, and Microsoft Edge to log messages, warnings, and errors. The Issues tool aggregates warnings from the browser in a structured, aggregated, and actionable way. The Issues tool links to affected resources within DevTools, and provides guidance on how to fix the issues.Over time, more warnings will be surfaced in the Issues tool rather than in the Console, to streamline the Console messages.To get started, see Find and fix problems using the Issues tool.Chromium issue #1068116View accessibility information in the Inspect Mode tooltipThe Inspect Mode tooltip now indicates whether the element has an accessiblename and role and is keyboard-focusable.Chromium issue #1040025See also:Analyze pages using the Inspect toolPerformance panel updatesSee also:Performance features referenceView Total Blocking Time information in the footerAfter recording your load performance, the Performance panel now shows Total Blocking Time (TBT) information in the footer. TBT is a load performance metric that helps quantify how long a page takes to become usable. TBT essentially measures how long a page only appears to be usable (because the content is rendered to the screen); but the page isn't actually usable, because JavaScript is blocking the main thread and therefore the page doesn't respond to user input. TBT is the main metric for approximating First Input Delay.To get Total Blocking Time information, don't use the Refresh Page workflow for recording page load performance.Instead, select Record , manually reload the page, wait for the page to load, and then stop recording.If Total Blocking Time: Unavailable is displayed, Microsoft Edge DevTools did not get the required information from the internal profiling data in Microsoft Edge.Chromium issue #1054381See also:Performance features referenceLayout Shift events in the new Experience sectionThe new Experience section of the Performance panel helps you detect layout shifts.
