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".
(thinking…)

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

Enter your idea and we'll search to see if someone has already suggested it.

  1. Provide actionable feedback

    Currently, the F12 provides a lot of information, but very little "actionable" feedback for developers. Tools like YSlow work on a defined set of rules and provide feedback. It would be extremely useful If the data collected from network, profiler and UI responsiveness tools can be combined into an actionable report for developers.

      • setDragImage on dataTransfer of DragEvent

        This has been overlooked sine IE 5.5, it has even made it way to the mobile IE (http://caniuse.com/#feat=dragndrop) but not the desktop one.

          • font-size-adjust & other font properties

            Add support for the CSS3 property used for adjusting font sizes consistently across font families. Supported in Firefox since the beginning.

            And please consider some of these font-related properties, too, potentially making it easier to customize and implement fonts on the web:
            * font-variant (and its children properties)
            * font-synthesis
            * font-kerning
            * @font-feature-values
            * font-language-override

                • <datalist> size and style

                  Hi,

                  I'm creating a contact form and I was using the <select> tag and I discovered the <datalist> tag and I think it's very useful, because it's dynamic (you can write and have some options at the same time). The problem is that I can't minimize the list of option with size="5" like with <select> tag. With <datalist>, I have like 30 options showing at the same time without scrollbar, so we can't see all of them...

                  My suggestion is to add css style like with <select> to change how the datalist look (color, shape, etc) and to be able…

                        • Gamepad API: Support Gamepad Vibration & Force Feedback effects

                          There is the proposed Gamepad API http://caniuse.com/#search=gamepad in development, however the specification does not have any planned means of utilizing vibration in gamepads.

                          It is a rather basic feature that enhances the gaming experience.
                          There should be a recommendation for it or prefixed functionality for IE. A complementary function to the API like myGamepad.setVibration(leftMotor, rightMotor) would be ideal.

                          In the future I'd also like to see a way to have force feedback effects for devices that support them, like Joysticks and Steering Wheels which would be useful for simulators and medical applications.

                          Thanks in advance!

                                • Transferable for postMessage in Web Worker

                                  The postMessage API for Web Workers in Chrome and Firefox supports a "Transferable" interface allowing certain types of objects such as ArrayBuffers and Typed Arrays to be "moved" from a worker context to the parent context, or vice-versa, without copying.

                                  This can be essential for good performance in image and video-processing tasks that need to ship around megabytes at a time.

                                    • Disable the tile version of IE via Group Policy or some other Enterprise management tool.

                                      Certain websites require add-ons that do not run in the tile version of IE in Windows 8.1+, thus causing the user to manually switch to the desktop version of IE. For end-user simplicity, it would be nice to have the ability to disable the tile version of IE via Group Policy or some other Enterprise management tool.

                                      • Option to expand the DOM Explorer "Computed" tab by default

                                        I would like to have an option to have the items in this tab expanded by default, or maybe an "expand all" button at the top so I can quickly toggle all items. It gets tedious constantly expanding them.
