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.

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.

        • 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

          • requestIdleCallback

            requestIdleCallback is the way that adopting requestAnimationFrame allowed us to schedule animations properly and maximize our chances of hitting 60fps, requestIdleCallback will schedule work when there is free time at the end of a frame, or when the user is inactive.

            • Support CSS Animation and Transition for SVG Properties on SVG Elements

              Support CSS Animations and Transitions for SVG Properties on SVG Elements like:
              stroke-dashoffset, stroke-dasharray, fill, stroke and so on.

              Example Animation CSS that should work:

              .svg {
              animation:svg-animation 1.5s ease-in-out infinite;
              }

              @-webkit-keyframes svg-animation {
              0% {
              stroke-dasharray: 1, 50;
              stroke-dashoffset: 0;
              }
              100% {
              stroke-dasharray: 50, 150;
              stroke-dashoffset: -100;
              }
              }

              Currently this example is working in all browsers except in Edge.
              I am not really sure if this is feature is SMIL, but since the animations are declared in CSS this shouldnt be really SMIL.

              Would be nice to get some feedback.

              Best regards,
              Rene

                              • Better image scaling. No more jaggies for downscaled images!

                                Responsive websites typically send a larger version of an image and then scale it down to match the available space on-screen. This is especially important in mobile when the user can change screen sizes without a reload by changing from portrait to landscape, for example. Even the Microsoft websites utilize this kind of responsive design.

                                What does this have to do with IE? Well if you do this with IE the insane image scaling will provide images so jagged even the largest fonts become unreadable.

                                In earlier versions of IE we could use a nonstandard CSS property to switch to…

                                • 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.

                                  • 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.

                                    • Mac version of Edge

                                      Produce a Mac version of Edge so developers on Mac can see how their work effects Edge users. This would also improve the user experience for people running Edge on Windows.

                                        • Bring `gap` property to flexbox

                                          As outlined in the linked issue, having the ability to use grid-gap on flexbox (which is soon to be renamed just "gap" by the CSS Working Group because "grid-gap" doesn't make sense when used on flexbox) solves a major pain point that developers are facing.

                                          See the issue for more details:
