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:

  • 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 the full set of apis for DocumentFragment

          Browser extensions such as Stylus/Stylish use templates which call .firstElementChild but we can't port these to Edge because the full DocumentFragment api isn't supported right now.

          • 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 DOM4 methods: prepend(), append(), before(), after() and replaceWith()

              Steps to reproduce the problem:
              1. Open the testcase http://jsbin.com/fiqacod/edit?html,js,output in Edge.

              What is the expected behavior?
              The test should pass.

              What went wrong?
              The test failed, indicating that Edge does not support the relevant DOM4 methods.

              • Implement HTMLLinkElement#relList and HTMLLinkElement#relList.supports

                In order to feature detect resource hinting rels like prefetch, preload, and dns-prefetch, please implement relList and relList.supports as added to the dom spec in https://github.com/whatwg/dom/pull/123 . relList.supports is implemented in current Firefox and Chrome browsers. It is not yet implemented in Safari, but the resource hinting is also not implemented, so feature testing for that is a true negative. However, Edge supports resource hinting, but feature testing is a false negative, which means developers have to resort to User Agent inference or forgo resource hinting, resulting in a slower experience for users.

                • 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]

                  • 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.

                    • 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.
