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.

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:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".

  1. 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…

      • Support KeyboardEvent.isComposing property

        https://w3c.github.io/uievents/#dom-keyboardevent-iscomposing

        This API is already supported on other desktop browsers. Supporting it will really makes IME handling easier.

        • ShadowDOM

          Implement ShadowDOM. I think it is already under implementation, but I didn't see it had any stars. Does it fall under the Custom Element category?

          • Suggestion: Element.scrollParent

            Suggestion: Element.scrollParent
            Returns the closest element which controls the position of current element with a scroll.

            This feature very useful in many cases, easy for browsers to implement and hard for plugins such as jQueryUI to get it right.

            Thanks

            • Implement XPath functions, e.g. position(), natively instead of using Wicked Good XPath

              All other things being equal, EdgeHtml (13.10586) seems to be about 5 times slower than IE11 (11.0.32) for simple XPath queries like a[position()=3]/b[position()=3]

              • Allow dom elements created on one window to be used in another (for popout windows)

                IE is the only browser that doesn't allow a element created on one window to be added to another. This is useful when creating popout windows in a web application and not all frameworks allow you to specify the document with which to create the element with.

                • Event.composedPath()

                  https://developer.mozilla.org/en-US/docs/Web/API/Event/composedPath

                  neither "path" nor the new standard "composedPath()" is supported at this point. it would be nice to not use polyfills just for IE & Edge while other browsers support it already for a while.

                  • CSS transform:matrix3d

                    I am creating a new JS UI framework which is using this style a lot.
                    Changing the value dynamically results in beautiful transitions in Chrome, FF & Safari. In Edge however, the animations feel 20x slower (I am not even sure if the GPU kicks in) and transitions like just zooming an image to the front results in flips & rotations which should not be there.

                    Please send me an email in case you need test cases and I can add you to the repository of the new framework to see it live inside the examples.

                    • Allow embedding a pdf from blob data

                      For now it's impossible to embed a PDF file generated either by a web API or client-side script.

                      "object" or "iframe" tags don't opens pdf document when the source is an objectURL or a dataURL.

                      See issue #5411066

                      Use case : http://pdfmake.org/playground.html

                      • Do not try to select entire words across different DOM elements

                        In response to this: http://stackoverflow.com/questions/35257641/stop-edge-browser-trying-to-select-words-across-elements/35267896#35267896

                        It would be nice to have the ability to control whether Edge tries to select entire words within a specific context. Perhaps using some (custom) CSS rule.
