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. Shadow DOM (unprefixed)

    Enables DOM tree encapsulation. Without it, widgets may inadvertently break pages by using conflicting CSS selectors, class or id names, or JavaScript variables.

        • APNG (animated PNG) images support [Firefox and Safari 8 support it]

          APNG is an extension of the Portable Network Graphics (PNG) format, adding support for animated images. It is intended to be a replacement for simple animated images that have traditionally used the GIF format, while adding support for 24-bit images and 8-bit transparency. APNG is backwards-compatible with PNG; any PNG decoder should be able to ignore the APNG-specific chunks and display a single image.

          GIF vs. APNG vs. animated WebP: http://littlesvr.ca/apng/gif_apng_webp.html

          • 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.

                On December 15th of 2011 Microsoft made a big change that largely goes unnoticed by the vast majority of users; updates to Internet Explorer began to happen automatically.

                Today, Microsoft continues to install the latest updates for Internet Explorer supported by the user’s operating system without getting in the way. With Internet Explorer 10 we also added a UI control to the “About Internet Explorer” window which gave the end-user easier control over this process.

                Understandably there are some situations in which auto-updates are not desired. For instance, enterprise customers may (and do) choose to opt-out of these updates due to a reliance upon older versions of Internet Explorer internally.

                Tasked with supporting legacy applications, while also supporting the advancing web, the Internet Explorer team developed Enterprise Mode for Internet Explorer 11. This feature is designed to grant the user all of the security and speed of a modern browser,…

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

                • Ogg Vorbis and Opus audio formats support [Firefox and Chrome support it]

                  Ogg Vorbis and Opus are free and open-source audio codecs with great quality. They are developed by Xiph.Org Foundation and IETF.

                  Opus codec provides the best quality (latest listening tests: http://listening-test.coresv.net/results.htm for 96 kbps and http://listening-tests.hydrogenaud.io/igorc/results.html for 64 kbps) and very low latency (http://opus-codec.com/comparison/ ). More information: http://en.wikipedia.org/wiki/Opus_%28audio_format%29 . Support status: http://caniuse.com/#search=opus .

                  Ogg Vorbis also provides good quality. It is an old audio format and you can find many of Ogg Vorbis files in the web. Ogg Vorbis is very popular in the Linux world. More information: http://en.wikipedia.org/wiki/Vorbis and http://vorbis.com/ . Support status: http://caniuse.com/#search=ogg .

                      • 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…

                                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.
