Microsoft Edge Developer

Hi, are you a web developer or designer?

“No, I just want to share feedback on Microsoft Edge.”

Please use the Feedback Hub (requires Windows 10) to submit your feedback in the Microsoft Edge category. This site is for web developer and designer feedback only. Other feedback will be closed without action.

“Yes, I’m a web developer or designer with feedback for the Microsoft Edge platform.”

Great! This site is where the Microsoft Edge team collects feature requests from the web developer and designer community in the categories listed to the right. For bugs on existing features, please log an issue on the Issue Tracker.

Your feedback will help us with planning and to better understand how web developers and designers are using the platform. Top standards-based feature requests will also be copied over to status.microsoftedge.com, where you can track its development status.

For the most actionable feedback, please search and up vote for existing suggestions before submitting a new suggestion, and create a separate suggestion per idea. Note that off topic or inappropriate suggestions may be moderated. The Microsoft Edge team will use suggestions as an important input, but there are several additional factors that inform the final roadmap.

A note from our lawyers: Please do not send any novel or patentable ideas, copyrighted materials, samples or demos which you do not want to grant a license to Microsoft. See the Terms of Service for more information.

How can we improve the Microsoft Edge developer experience?

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  1. Do not close F12 Dev Tool window on site load and redirects

    The F12 window gets closed when opening a website or during auth redirect, which makes it impossible to debug auth failures and JS errors happening during website initialization.

    • add/edit/delete specific cookies

      Both Chrome and Firefox allow developers to manage cookies.Our QA and QE need some cookie editing tools that are more accessible than the console.

        allow easily design responsive page using media query by emulating different resolutions (like the way Chrome does - Device emulation)

          • Improve overall performance

            Every time I open the Dev tools the browser slows a lot and crash often especially with heavy sites. This do not happen with Chrome.
            Resizing the view also is incredibly slow and stuck my workstation.

            This makes it almost impossible to use even if I would gladly use it instead of the Chrome one

            • Show upload size in Developer Tools Network Panel

              Steps to reproduce the problem:
              1. open the devtools network panel
              2. upload a file using html file upload

              What is the expected behavior?
              The size of the upload to be visible for the individual network request and also counted in the status bar transfer summary

              • Allow F12 tools to be extended with Browser Extensions

                I have currently built a browser extension for Chrome that allows me to add a new pane to the DevTools that has its own UI and can communicate with the current tab with a background page for the extensions.

                I would like to be able to write the same extension for Edge. That allowed me to do the same.

                • Prevent developer tools from causing "(not responding)" and non responsive main UI thread

                  Currently when I open and close developer tools its often puts edge into an apparent "not responding" state for a few seconds. This makes the platform seem very low quality despite the fact edge in general is great.

                  This also has the effect of if you are paused in a debugging session on a breakpoint you cannot just press F5 to refresh the page you have to stop the debugger since the UI is locked up... Chrome/Firefox/Safari doesn't do this.

                  • Support colored logs styles in console

                    Chrome and Firefox support styling the console text.
                    I use the feature a lot and I would really appreciate to have it in Edge.

                    • F12 Developer Tools: Add font settings option

                      I feel the DOM Inspector font as being too large when I'm debugging web pages having a number of windows (incl. web page and F12 window) spread across the screen. In the restricted space available for the F12 window (particularly when it's docked to the bottom of the browser window) I can hardly get to see three lines of HTML.

                      So, please add a Font Settings option to F12DT so I can choose a smaller font size for DOM inspector and other F12DT panels, resp.

                      And please add a Boolean option for disabling word wrap in DOM inspector.

                      • Automatically open dev tools for a new tab prior to opening the site.

                        When working with links that open in a new tab, I have to start the dev tools after the site starts loading for that tab. If I have dev tools open in the previous tab then start dev tools in the linked tab so I get the initialization. Starting the dev tools after the tab starts means the tools aren't running when that site loads. Add it as an option in the about:flags page.

                          • Emulation: Throttle CPU

                            This feature would extend the emulation tool to enable throttling of the CPU to emulate situations where the page is running on a low CPU device. The emulation is not perfect (e.g. it wouldn't emulate diff instruction sets) but would help in giving a more real world experience for lower powered devices (desktop and phone).

                                  This feature would use some rule checking against the acc tree and properties to point out potential issues. For example when an img is missing a name (say because of a missing alt attribute) or a labelledby is pointing to an invalid node etc.

                                    This feature would articulate how the various accessibility properties in the accessibility panel are calculated. For example where the name value comes from.

                                    • Being able to activate element highlighting when the page is focused

                                      As the title says, being able to activate the element highlighting after interacted with the page would be very useful

                                      • Don't remove combined files after loading source maps

                                        Currently in the debugger, after the source maps are loaded, the combined javascript files are removed from the source tree which makes following up production stack traces challenging.

                                        Firefox has a similiar problem https://bugzilla.mozilla.org/show_bug.cgi?id=1301331

                                        • Add the 'copy' console API to copy variable contents to clipboard

                                          Firefox and all webkit-based browser have a 'copy' function injected into the console, which can be used to copy the content of any variable currently in the console to the clipboard. I recently discovered this in Opera, and it's become a very handy functionality. Please add this to Edge too.
