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.

      • Please be careful with making Edge Chromium-based

        I've recently read articles about the engine of Edge is being replaced by Chromium.

        I don't think this is a good idea. Microsoft Edge manages to do what no browser can do. It plays online HTML5 videos with the speed and low-resource need comparable to a native video player (like VLC or Media Player Classic).

        This is YouTube playback in Chrome and Edge compared, on the same hardware.
        https://www.youtube.com/watch?v=lu1VuKTCOK8

        Chrome and Chromium are famous about having a very catastrophic, bloated multimedia backend, especially when it comes to video playback. GPU acceleration is hardly compatible with any video hardware. Also it…

              • Add Support for S/MIME in Microsoft Edge

                Idea: Add support for S/MIME in Microsoft Edge browser. Since Microsoft Edge is the successor to IE in some regards I'm confused as to why they didn't add support for S/MIME. I, like many other government or business employees rely on this for viewing/sending encrypted mail.

                I do love the edge browser because it works so much better Outlook Web Access but not having the ability to install S/MIME really takes away from the experience.

                Has there been any discussion thus far as to why this hasn't been implemented?

                  • Fully implement the FormData API

                    Currently the FormData API is only partially implemented in Edge. Most of the more useful methods are missing including: has(), get(), set(), delete(), entries(), and many others.

                    FormData is already fully implemented on the other major browsers (Firefox, Chrome, Safari) - see: https://developer.microsoft.com/en-us/microsoft-edge/platform/catalog/?q=formdata

                      • Mac version of Edge

                        Produce a Mac version of Edge so developers on Mac can see how their work effects Edge users. This would also improve the user experience for people running Edge on Windows.

                        • Bring `gap` property to flexbox

                          As outlined in the linked issue, having the ability to use grid-gap on flexbox (which is soon to be renamed just "gap" by the CSS Working Group because "grid-gap" doesn't make sense when used on flexbox) solves a major pain point that developers are facing.

                          See the issue for more details:

                          • Aggressively promote the replacement of HTTP with HTTPS

                            The video linked below makes it very clear on why HTTPS should always be used instead of HTTP.
                            https://www.youtube.com/watch?v=_BNIkw4Ao9w

                            Currently, all that happens in Microsoft Edge when you connect to a web page through HTTP is that a "🛈" icon appears in the address bar. Since the web page still works, there is little pressure on web developers to drop support of HTTP in favour of using HTTPS. In essence, by treating HTTP almost identically to HTTPS in Microsoft Edge, Microsoft is not doing its part in promoting a safer, more secure, privacy-respecting Internet.

                            Microsoft should be a leader—more aggressive…

                            • Allow SendKeys to an <input type="file"> for file uploading

                              Using the WebDriver for Edge, and trying to use SendKeys to affect an <input type="file">, we get an error message that the element isn't focusable.

                              This is something that works in other browsers. It's the simplest way to upload a file in Selenium since WebDriver can't interact with a file dialog on the desktop.

                              This has been reported as an issue before:

                              https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/7194303/

                              ...but the only response has been "fixed internally" a year ago, which doesn't help those of us who don't work for Microsoft.

                              If Edge is important to Microsoft, then you'll want web sites to work with it.…

                                    • Support the `inert` attribute

                                      Trapping focus in modal dialogs or preventing focus in background layers in modern web applications is extremely difficult and error-prone. Developers either have to walk the DOM and disable every focusable control with tabindex="-1" and `aria-hidden="true"` on a parent element, or do some tricky JavaScript to maintain focus inside of an element. Many developers get this wrong or they don't do it at all, creating horribly inaccessible experiences for keyboard and screen reader users.

                                      The inert attribute currently being explored in the WICG solves this problem by providing a mechanism to disable entire subtrees in HTML. By setting `inert` on…

                                      • lazyLoad

                                        Currently, LazyLoad ( https://msdn.microsoft.com/en-us/ie/dn369270(v=vs.94) ) is implemented in IE and Edge, see support: https://caniuse.com/#feat=lazyload

                                        However there is interest in standardization to enable developers lazy-loading images/iframes and other embedded content (and the proposed lazyLoad's attribute values differ from that of current Edge/IE implementation):

                                        • include browser version in user agent string

                                          Microsoft Edge on windows does not include the version of the browser but only the version of layout engine:

                                          Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.140 Safari/537.36 Edge/18.17763

                                          The version should be 44.17763.1.0, since 18.17763 is the version of layout engine

                                          I suggest something like:

                                          Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.140 Safari/537.36 Edge/44.17763.1.0 (EdgeHTML 18.17763)
