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".

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.

    • indexedDB explorer in dev-tools

      It would be nice to see the indexedDB database in dev-tools.
      Think about:
      * Version
      * ObjectStores
      * Data in objectstores
      * Indexes for objectstores

      • Improve video event and seeking mechanisms

        Some things are handled not correctly regarding the HTML5 video abilities:
        - IE does not fire the resize event
        - no waiting event on buffer underrun
        - canplay and canplaythrough events are missing if you seek
        - pause event is missing after the playback ends
        - seeked event is fired without change of the image (in 86% of all cases)
        - timeupdate is fired in waiting state

        Please work on a more robust video API. A more elaborated description can be found at http://www.ronpub.com/publications/OJWT-v1i2n01_Hoernig.pdf

        • 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.

              • Support PNG, GIF & SVG cursors and other cursor enhancements

                Add support for more formats than just the CUR and ANI file formats in the CSS cursor property. PNG, SVG and GIF support would be good.

                Also, consider supporting the zoom-in/out and grab/grabbing properties, in addition to updating the browser-specific cursors like no-drop, all-scroll, col/row-resize, alias, cell, copy and context-menu cursors, as they look small/jagged, old and weird on my high DPI screen.

                    • Enable "macros" or tools to playback bug reproduction steps that can be saved, shared and perhaps even extended with custom code.

                      Are you familiar with the popular POSTMAN Chrome extension? It's a super simple tool for defining and saving HTTP requests for playback. While that's nice in itself, what about taking things much further by allowing developers to create 'macros' or custom scripts to run in IE dev tools to help automate things like test cases, bug reproduction steps or more esoteric things like scripts to collect diagnostic information from (nontechnical) clients.
                      It would be nice to have a super-simple way to create scripts to automate tasks *specific* to developer scenarios. (Without the overhead of custom browser extensions and such.)

                      • Better memory management

                        Improving memory management would prevent IE from blowing through all available graphic memory. Often, when using a high number of tabs (common in development), IE will overload the available graphics memory (never RAM), and elements will start disappearing from web pages or failing to load altogether.

                        This needs to be tweaked so that it stops happening - it doesn't seem to be an issue for any other browser.

                        • Implement <table sortable>

                          It is a common use case with data tables that one would like to sort the data, to order by a particular column (or multiple columns.)

                          Currently this must be done via JavaScript, but HTML5.1 has the `sortable` attribute for <table> [1] and the `sorted` attribute for <th> [2]

                          [1] http://www.w3.org/html/wg/drafts/html/master/tabular-data.html#attr-table-sortable
                          [2] http://www.w3.org/html/wg/drafts/html/master/tabular-data.html#attr-th-sorted

                          • Support C++ Native client (PNaCl/NaCl)

                            Pnacl is fast! (10 times faster than js, 66% faster than asm.js)
                            Pnacl is portable! (LLVM)
                            Pnacl is secure! (Forget about ActiveX, this is sandboxed!)
                            Pnacl is mature! (with Pepper, interact the way you want with the browser)
                            Pnacl is NOT an hack! (There is no heavy js transaltion, it support native multi threading, native long type, there is no crazy code deletion, you can easily debug your code, you don't have to bind class, etc...)

                            So i know that the ie team will just ignore this request (it's a lot of work to implement it), but i just wanted…

                            • Provide actionable feedback

                              Currently, the F12 provides a lot of information, but very little "actionable" feedback for developers. Tools like YSlow work on a defined set of rules and provide feedback. It would be extremely useful If the data collected from network, profiler and UI responsiveness tools can be combined into an actionable report for developers.

                                    • font-size-adjust & other font properties

                                      Add support for the CSS3 property used for adjusting font sizes consistently across font families. Supported in Firefox since the beginning.

                                      And please consider some of these font-related properties, too, potentially making it easier to customize and implement fonts on the web:
                                      * font-variant (and its children properties)
                                      * font-synthesis
                                      * font-kerning
                                      * @font-feature-values
                                      * font-language-override
