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.

    • Support for @counter-style

      Related w3 document:
      https://www.w3.org/TR/css-counter-styles-3/

      The Internationalization WG observes that Edge does not pass the tests found here:

      See https://www.w3.org/International/tests/repo/results/counter-styles.en.html (click on the large text in the left-most column to run the tests)

      Several groups have observed the need for counter style support. The Arabic Layout TF finds that it is needed for Persian support. Richard Ishida reports that vertical text lists require it as well. Firefox is observed to provide this support.

          Can I download Edge version 13 on Windows 10? If so, do I have to uninstall Edge 14 first? This is for compatibility testing.

          • support web components (v1) standard

            web components standard present a modern way to create cross-framework compatible components. This should reduce the effort and cost of many enterprise companies that build their own component library and porting frameworks.

              If I open the file upload window without specifying the accept attribute, it will accept all files.
              However, an option list is created so that you can select another type.

              The first attachment is the pre-requested file. The second attachment is what you want.

              • Implement CSS `display: flow-root` (modern clearfix)

                `display: flow-root` is a modern way to force a block to be a formatting context that floated elements are contained in (aka clearfix).

                From the spec [1]:

                > The element generates a block container box, and lays out its contents using flow layout. It always establishes a new block formatting context for its contents.

                Tab Atkins and Elika Etemad (fantasai) from CSSWG consider the feature stable enough to be implemented [2].

                • A way of automatic installation of extensions

                  All other major web browsers (Chrome, Firefox, and Internet Explorer) provide some way to install an add-on/extension by the application installer. Most antivirus programs and download managers make use of this capability.

                  With Edge, the end user, after installing the main application, has to go to the Store and add the corresponding Edge extension manually herself.

                  There should be way for the extension publisher to obtain Microsoft-signed extension package from the Developer Dashboard, and include it along with the main application installer, to be added later to users' systems by powershell's Add-AppxPackage, or its equivalent.

                  • Support the Device Memory API

                    It’s still in development, but the Device Memory API (https://github.com/w3c/device-memory) would be a relatively easy implementation that could enable "lite" versions of page assets.

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

                        • UI interface for dns resolving

                          I understood that because edge runs in a sandbox, it has problems using the hosts file.

                          Maybe we can have an u.i. where we can set where the domains have to resolve to. So we don't need the hosts file anymore.

                            When I'm debugging mapped source files and I hover over variable, I want to see the variable value.

                            Let's say I have ES2015 or TypeScript souce code, babelified, minimized and browserified. In chrome I can debug the original source code and inspect the variables. I would love to see it in Edge too.

                            • Implement the update media feature from MQ4

                              The update media query from Media queries level 4 let people tell apart media that responsively update the screen, from those that cannot, or those that can but only slowly.

                              Authors can use that to style things differently on print vs ebook readers, even though both media are paginated. This kind of nuance was not possible to express just with @media print {...}

                              The specification is over here:

                              • Implement the overflow media features from MQ4

                                The overflow-block and overflow-inline media queries from Media queries level 4 let people tell apart media that paginate vs media that scroll or media that clip using media features instead of media types.

                                That way, you can do

                                @media (overflow-block: paged) {
                                /* do something smart for pagination */
                                }

                                and that will do the right thing when printing AND in ebook readers that paginate instead of scrolling, instead of

                                @media print {
                                /* do something smart for pagination */
                                }

                                which would work on print but fail in ebook readers.

                                The specification is over here:

                                • 3DES only available for local domains/router segments/local networks if needed. NOT FOR THE INTERNET.

                                  SCHANNEL : The 3DES Cipher should be used - if needed at all - ONLY selectively and definitely kept blocked - disabled - for Internet Connections ranging outside of a local Network boundary (or outside of proxied Segments or NAT Domains or also when not being used through either encrypted VPN Tunnels).
                                  I recommend this because it is weak. (64bit ciphers are generally considered weak now because of their limitation).

                                        • Add support for CSS printing hints

                                          Other browsers support some level of CSS hints for printing to hint to the browser to use landscape over portrait, and what margins to use.
