Microsoft Edge, the Chromium-based browser developed by Microsoft, has steadily evolved into a robust, modern browser that caters to casual users and power users alike. While the browser ships with a clean interface and numerous built-in tools such as Collections, Vertical Tabs, and a Reading Mode, there exists a more experimental side of Edge that many users aren’t aware of. This is accessed through “Edge Flags.” Microsoft Edge Flags are experimental features, tools, and settings that users can toggle to enhance their browsing experience. These flags are typically in testing or development stages and may eventually be included as standard browser features in future updates—or removed entirely if they prove ineffective or unstable.
If you’re someone who enjoys customizing your browser for performance, productivity, or cutting-edge functionality, delving into the world of Edge Flags is a worthwhile endeavor. In this guide, we’ll explore how to enable Edge Flags, their benefits, popular and useful flags to try, and best practices for using them responsibly.
What Are Microsoft Edge Flags?
Microsoft Edge Flags are hidden settings that enable users to test features that are still in development. These experimental flags can provide access to advanced options that may improve performance, user interface elements, privacy, developer tools, and more. These settings are typically used by developers, beta testers, and tech enthusiasts who want to try out new functionalities before they are officially released to the general public.
The flags are built on top of the Chromium engine—the same open-source platform used by Google Chrome—so Edge inherits a wide variety of Chrome’s experimental features while adding Microsoft’s own innovations. Flags can be incredibly useful for users looking to push the boundaries of what Edge can do. However, since they are experimental, enabling them may sometimes cause instability, browser crashes, or incompatibility with certain websites. Therefore, users should be cautious and enable only the features they truly need or wish to explore.
How to Enable Microsoft Edge Flags
Accessing and enabling Microsoft Edge Flags is a straightforward process, but it’s important to follow the steps carefully to avoid enabling incompatible or unstable settings. Here’s how to do it:
- Open Microsoft Edge on your Windows, macOS, or Linux device.
- In the address bar, type
edge://flags
and press Enter. - You will be redirected to the Experiments page, which contains a list of all available flags.
- Use the search bar at the top of the page to find a specific flag or browse through the list manually.
- Next to each flag, you’ll see a drop-down menu that typically says “Default.” Click it to select Enabled, Disabled, or Default.
- After enabling or disabling a flag, you’ll see a “Restart” button at the bottom of the page. Click it to relaunch the browser and apply the changes.


It’s that simple. The changes take effect immediately upon restart, and you can always revisit the edge://flags
page to reset any flags back to their default state.
Key Features of Microsoft Edge Flags
Edge Flags allow users to enhance virtually every aspect of the browser. Here are some of the major feature categories affected by flags:
1. Performance Optimization
Some flags allow users to tweak how the browser handles rendering, tab suspension, GPU usage, and more. These tweaks can significantly improve browsing speed and efficiency, particularly on older or lower-spec devices.
2. User Interface Customization
UI-based flags allow for changes to how tabs are displayed, changes to themes, experimental layouts, and how specific components like toolbars or context menus behave.
3. Privacy and Security Enhancements
Certain flags let users enable enhanced tracking protection, isolate processes for individual websites, or experiment with secure DNS features.
4. Developer Tools and Debugging
Flags also provide advanced options for developers, including experimental JavaScript engines, network debugging tools, and pre-release rendering features that help during the testing phase of web development.
5. Experimental Web Technologies
Some flags offer support for future or upcoming web standards, like HTTP/3, QUIC, or WebGPU, giving developers early access to next-gen web capabilities.
6. Accessibility Improvements
There are also flags dedicated to improving accessibility features like screen reader support, visual contrast tools, and text-to-speech capabilities.

Caution and Best Practices When Using Edge Flags
While flags can provide powerful enhancements, they come with caveats. Since these are experimental features, Microsoft doesn’t guarantee they will be stable or safe for daily use. Here are some best practices:
- Use One Flag at a Time: Don’t enable multiple flags simultaneously without testing them individually first. Some flags may conflict with others.
- Document Changes: Keep a note of the flags you’ve enabled and their original settings. This will make it easier to troubleshoot issues.
- Don’t Use in Critical Environments: Avoid enabling experimental flags on business-critical systems or machines where reliability is paramount.
- Reset When in Doubt: If the browser starts misbehaving, go to
edge://flags
and click “Reset all to default.”
Frequently Asked Questions (FAQs)
1. Are Microsoft Edge Flags safe to use?
Microsoft Edge Flags are generally safe to experiment with, especially for casual users who want to tweak performance or layout settings. However, because they are experimental, they can introduce instability or unintended behavior. It’s best to use them in non-critical environments and always keep track of what you enable.
2. Do Edge Flags affect browsing speed or performance?
Yes, some Edge Flags can significantly improve speed and performance, such as Sleeping Tabs or Parallel Downloading. However, others might have the opposite effect, particularly if they introduce features not yet optimized. It’s essential to monitor performance after enabling new flags.
3. Will my changes to Edge Flags be saved after updates?
Most flag settings persist after browser updates, but since flags are experimental, Microsoft may remove or change them without notice. If a flag is deprecated, it will be reset or removed automatically in future versions.
4. Can I use Edge Flags on mobile versions of Microsoft Edge?
Yes, some Edge Flags are also available in the mobile versions of the browser (Android in particular). You can access them by typing edge://flags
in the address bar on your mobile device. However, the list of available flags is typically more limited than on desktop.
