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. img decoding attribute

    https://html.spec.whatwg.org/multipage/embedded-content.html#attr-img-decoding

    > Decoding of large images can block the main thread for hundreds of milliseconds or more, interrupting fluid animations and user interaction. Currently, there's no way for a web author to specify that they want an image to be decoded asynchronously, so there are scenarios where it is impossible to avoid UI stalls.

    Thus the new `decoding` attribute for the `img` element, with possible values:

    * `sync`: Indicates a preference to decode this image synchronously for atomic presentation with other content.

    * async: Indicates a preference to decode this image asynchronously to avoid delaying presentation of other content.

    *…

    • Implement link rel="modulepreload"

      modulepreload is a new link relation that behaves similar to preload, but different in several key ways. For example, it interprets its attributes and changes to them differently; it uses the module map instead of the preload cache; and it allows optionally fetching descendant modules as an optimization.

      Spec: https://html.spec.whatwg.org/multipage/links.html#link-type-modulepreload

      Tests: https://github.com/w3c/web-platform-tests/blob/master/preload/modulepreload.html

      • Support Feature Policy

        https://wicg.github.io/feature-policy

        Feature policy is a mechanism for developers to enable and disable web platform features on their sites, in their pages and in third-party content which they have framed.

        It allows control of existing features such as XMLHttpRequest and geolocation, as well as new features such as WebVR

        • Support bidi isolation for elements with dir attributes, and for bdi

          This is a specific request for Edge to support bidi isolation per the HTML specification where the dir attribute and the bdi element are used. The wording in the request for dir=auto [1] is equally valid here.

          Support for isolation is really a fundamental requirement for languages using Arabic and Hebrew and other scripts such as Thaana, Syriac, N'Ko, etc. Note also that the Arabic script is the second most widely used script around the world after the Latin script, so this affects a lot of people. And the lack of isolation is not an edge-case problem (see worked examples…

          • Add ability to type in into input type="date" and input type= "datetime-local"

            Add ability to type in into input type="date" and input type ="datetime-local" as:
            1. By default the range in the datepicker is restricted +/- 100 years which is not always the case
            2. Changing min/max attribute crashes the browser
            3. Overall it would be more user friendly to just type in the value in some case with huge distance between actual and expected value

            The case: actual value 12/31/9999 being change, expected value 12/31/2017 (the one to be changed to)

              • <datalist> searches using "contains" instead of "starts with"

                Firefox (since ages) and Chrome (since 08/2016) search datalist items using "contains". However, IE still uses "starts with" to filter datalist items.

                It can easely be tested here:
                http://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_datalist

                I think IE should adopt a "contains" approach too to filter items, as it is by far more useful/practical ...and would behave similarly to FF/chrome.

                    • Support a[download] attribute for data URIs

                      The download attribute doesn't appear to be used when downloading a hyperlink containing an href like the following:

                      <a id="a" href="blob:E0F5CA16-F4AA-4B18-9A07-BFDD1F0633BD" type="text/plain" download="test.txt">Download</a>

                      $('#a').attr('href', URL.createObjectURL(new Blob([data])));

                      Instead, the downloaded file gets the filename "E0F5CA16-F4AA-4B18-9A07-BFDD1F0633BD".

                          • Support dir="auto"

                            dir="auto" dramatically simplifies dealing with variable and user-generated content whose language is not known.
                            It'd also allow site generators that convert from formats like Markdown to almost automagically support mixed-direction document with almost no changes to the generator — they just has to slap dir=auto all over the place. While not perfect, it's about the best that can be done when the input doesn't contain language information.

                            Doc: http://www.w3.org/International/articles/inline-bidi-markup/#dirauto
                            Spec: https://html.spec.whatwg.org/multipage/dom.html#the-dir-attribute

                            • Multi lingual string formatting

                              Multi lingual string formatting - when text is rendered within a table cell and direction is set to rtl the text wraps in a ltr centric manner.

                              The text seems to start from the bottom right of the cell and finish at the top left, when it should go from the top right to the bottom left.

                              For example - If I use integer values to show each characters position in a string a left to right string might look like so -
                              1 2 3 4 5 6 7 8 9 10

                                • Meta theme-color

                                  Support Meta theme-color for filling the role msapplication-TileColor, bringing back the role of msapplication-navbutton-color (if those meta tags aren't present) and also setting the color of the status bar on Edge Mobile.

                                  And maybe something new like changing the color of the tab itself on the Edge browser.

                                  • Implement DOM accessKeyLabel

                                    Standard specification at https://html.spec.whatwg.org/multipage/interaction.html#dom-accesskeylabel

                                    Already implemented in Mozilla Firefox.

                                    Implementing this in Microsoft Edge would improve performance for websites using this (such as Wikipedia) by not having to load a polyfill that infers this information based on heuristics such as User-Agent strings and OS information.

                                    This is a simple property accessed through the DOM that returns a string representing the keyboard combination used for access keys. This varies from browser to browser and between different operating systems and devices (mostly desktop however).

                                    • Repair work of selectionStart/selectionEnd properties for inputs and textareas

                                      The properties selectionStart and selectionEnd work incorrectly. Their values fail to match the real selection state after certain operations with elements (inputs and textareas).
                                      Consider a page with an input element (type="text", value="12345", not activeElement). After you call el.setSelectionRange(2,2), what you get is el.selectionStart = 0 although the cursor is positioned correctly.

                                      • Additional atributes for reading mode

                                        Hi! I've noticed that the reading wiev of Edge does not by default support rendering pictures and SVG content. Can you consider adding optional HTML attribute for when we WANT the content to be accessible when the user opts to view our page in Reading mode? It would be most helpful for instructions, HowTo's and other content where images are a must.

                                        • autocapitalize attribute

                                          Gives a hint to the virtual keyboard regarding the preferred autocapitalization behaviour.

                                          Proposal: https://github.com/mounirlamouri/html-autocapitalize/blob/master/proposal.md
