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".

      • Subresource Integrity

        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.

              • 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.

                • 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…

                  • Ajax caching working like other browsers

                    Internet Explorer caches ajax responses too agressively. In the modern SPA world, everything is working through AJAX request, so it is more and more important, to not cache automatically all of the AJAX responses. Firefox and Chrome is working normal with AJAX responses, only IE caches too agressively.

                            • Support TLS to the proxy

                              Both Chrome (http://www.chromium.org/developers/design-documents/secure-web-proxy) and now Firefox 33+ support connecting to a CERN-style proxy over TLS instead of using unencrypted sockets (https://bugzilla.mozilla.org/show_bug.cgi?id=378637). They've also enhanced the Proxy AutoConfig system to support the "HTTPS" token instead of the "PROXY" token, meaning that organizations could conceivably start to deploy PAC files that work for other browsers but fail in IE.

                              WinINET should consider adding TLS-to-the-Proxy for Interop and for the reasons described in the Firefox bug.

                                • Support certificate validation using DANE (RFC 6698)

                                  DNS-based Authentication of Named Entities (DANE) complements and sometimes replace the current trust model for certificates. Since it is based on the hierachical DNSSEC system, it doesn't have the flaw of having numerous (and sometimes a bit untrustworthy) certificate authorities all able to issue certificates for any domain. By making CAs unnecessay for domain-only certificates, it would shift their market to providing more reliable validation of additional information, such as who is the owner of the domain.

                                  • SSL key logging (aka SSLKEYLOGFILE)

                                    SSL key logging is a feature that browsers export TLS keys into a text file, which can be used by Wireshark to decrypt TLS traffic. This feature can be enabled on Firefox and Chrome by setting SSLKEYLOGFILE environment variable, which is a path to the log file.

                                    This feature is useful for debugging network error and for learning structures of TLS-encrypted application layer protocols (such as encrypted HTTP/2) with Wireshark.

                                        • Support Chrome's improved reload behavior or cache-control:immutable

                                          Both Chrome and Firefox have improved the performance of the reload button. Chrome no longer revalidates subresoruces on reloads. Firefox supports the cache-control:immutable header as a way for sites to signal that they do not want their sub resources revalidated before their expiration

                                          Facebook's internal statistics show that browsers that do not support this behavior cause 10-20% more requests for JS/CSS because users use the reload button to refresh the site.
