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. 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
    Support status: http://caniuse.com/#feat=apng (Firefox and Safari 8 support APNG)
    Specification: https://developer.mozilla.org/en-US/docs/Animated_PNG_graphics

                      • Support WebRTC Datachannels in Workers

                        I would like to propose that we support WebRTC Data Channel in Workers
                        (`WebWorker`, `ServiceWorker`, etc.)

                        WebRTC DataChannel is basically a drop-in replacement for `WebSocket`,
                        except it's peer-to-peer. For all the same reasons that `WebSocket`
                        was added to the `Worker` spec, we should add WebRTC DataChannel.

                        Here are some possible use cases:

                        - DataChannel in a `ServiceWorker` would support the use case of "peer
                        assisted delivery" a la [PeerCDN](https://www.peercdn.com/faq.html),
                        CDN/P2P CDN video streaming delivery, file transfer, etc.

                        - DataChannel in a `WebWorker` would support offloading CPU intensive
                        data transfer and subsequent processing to another thread.

                        - DataChannel in…
