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.

    • Service Worker

      ServiceWorkers (formerly Navigation Controllers) are a new system that provides event-driven scripts that run independent of web pages. They are similar to SharedWorkers except that their lifetime is different and they have access to domain-wide events such as network fetches.

          OGG, Theora and Vorbis are now supported in the Fall Creators Update by installing the Web Media Extension from the Microsoft Store: https://www.microsoft.com/store/apps/9n5tdp8vcmhs

          Long-term, we expect to expand distribution of the Web Media Extension package to all Windows 10 devices so that these formats become a trusted and reliable part of the web platform available to developers.

              The template element shipped in EdgeHTML 13 as part of the Microsoft Edge version included in Windows 10 build 10586 (November 2015).

              For more information on our Web Components plans you can visit http://blogs.windows.com/msedgedev/2015/07/14/bringing-componentization-to-the-web-an-overview-of-web-components/ (part 1) and https://blogs.windows.com/msedgedev/2015/07/15/microsoft-edge-and-web-components/ (part 2)

            • position: sticky

              position: sticky is a new way to position elements and is conceptually similar to position: fixed. The difference is that a stickily positioned element behaves like position: relative within its parent, until a given offset threshold is met.

                    I created a CSS-based grid system for my SVG sprite sheet using transforms, only to revert to transform attributes after it collapsed in IE9+.
                    Please add support for CSS transformation in SVG.

                              Subresource Integrity defines a mechanism by which user agents may verify that a fetched resource has been delivered without unexpected manipulation. In a nutshell, metadata inlined into HTML elements allows the browser to determine whether the resource that was downloaded matches the resource the page's author expected to download.
