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".

    • File API support for extensions

      One great addition to Edge extensions would be the ability to write files .

      There are of course security issues related to reading or writing files to the file system, but at some point, Edge will support the Downloads API (6 out of the 20 most popular Firefox extensions rely on this API). This API (chrome.downloads) allows to write a file to the Downloads folder out of an external URL. Why not then allow an extension to generate files limited to that folder ?

      That would allow saving videos (some streaming protocols need processing so the Downloads API is not…

        • Downloads API support for extensions

          Missing Downloads API support is not good. I wanted to port my extension but it relies on basic downloads API missing in Edge.

          • Implement CSS `display: flow-root` (modern clearfix)

            `display: flow-root` is a modern way to force a block to be a formatting context that floated elements are contained in (aka clearfix).

            From the spec [1]:

            > The element generates a block container box, and lays out its contents using flow layout. It always establishes a new block formatting context for its contents.

            Tab Atkins and Elika Etemad (fantasai) from CSSWG consider the feature stable enough to be implemented [2].

              • RTC Data Channels

                Data channels allow a web application to send and receive generic application data peer-to-peer.

                This feature request is specifically about the *data channel* component of the WebRTC specification. This is separate from Object RTC and WebRTC 1.0 feature requests because the Platform Status site breaks out data channels separately.

                • WebVR : Add support for Oculus Rift, OpenVR and OSVR

                  WebVR is now supported by the latest version of Edge in the Creator Update and that's amazing. However, it is limited to Mixed Reality Devices and those devices and they are not available. Windows 10 users who already have a VR headset such as a Rift or a Vive, have to use a beta browser to enjoy WebVR.

                  Please considere to update Edge with at least a support for the Oculus Rift and the Vive. And only if you want to be a super hero, add OSVR support too.

                  • Enable whitespace trimming for Get Element Text in Microsoft WebDriver for Edge

                    In Edge WebDriver, the get element text always show extra whitespace characters as prefix and/ or suffix. Probably it returns an element's text as rendered using innerText. This is not in line with other webdrivers like Chrome, Safari and "Microsoft" IE webdriver.
                    Will be good if you can fix it to trim the extra whitespace characters by default. Will be very helpful, Thanks!

                            I know you've tried to GC the native code, but it's not enough.

                            There are still UAF bugs. There are still type bugs. It's time to put an end to them once and for all. Write in managed code. We know that Microsoft can create environments that are type safe; it's time to actually use one.

                              • 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)

                                  • Display: contents

                                    Display: contents is incredibly useful when working with grid and flexbox. It is already implemented in Firefox and works really well.
                                    It allows ancestors that are not direct children to become flex-items or grid-items.

                                    • Suport "appearance: none" for <input>

                                      Would be nice if Edge supports appearance (or -webkit-appearance) set as 'none' for <input> elements, like radio or checkbox.

                                      • Implement 'once' event listener option

                                        The DOM Standard defines a 'once' option for addEventListener() which causes the callback to only be called once, upon the next occurrence of the given event type, after which the listener gets automatically removed:
                                        https://dom.spec.whatwg.org/#dom-addeventlisteneroptions-once

                                        The effect is similar to jQuery's popular $.one() method.

                                        • Suport for calc in rotate/scale/for time vals

                                          But there's still something missing & with vars now supported, it's more important than ever: calc in rotate/scale/for time vals.
