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.

      • Wrong inheritance with SVG's fill-opacity

        In IE11, if the path element of SVG has "fill-opacity" and the element is using a marker, the opacity would be inherited by marker (although marker element is NOT the child of path).

        • IE performance: TryCatchWithErrors and LayerMovement Test

          On this test, http://jsbin.com/buruseri/, IE11 performs poorly compared to other browsers especially in TryCatch and LayerMovement stress tests.

          Note: The result may vary on each run but the results shown below give you a general idea about the difference in performance on same PC.

          Time taken to accomplish this test by various browsers is as follow:

          Results:

          Safari 5.1.2

          Try/Catch with errors — 8
          Layer movement — 5
          Random number engine — 6
          Math engine — 16
          DOM speed — 8
          Array functions — 3
          String functions — 3
          Ajax declaration — 3

          Total Duration 52 ms

          • Have the tools take focus on the first click

            When I have the tools open, but I'm interacting with another window, it takes two click on the developer tool's header before it will do anything.

            So if I want to move the F12 tools and I'm currently interacting with a tab in IE (not the tools), I have to click once on the header of the F12 tools and then click again before it will let me drag it around.

                • Ask for SSL certificate only once per request cycle.

                  When accessing a REST interface over https using a client cert, IE will ask for the certificate multiple times during the first request cycle if multiple requests are done. After the first request however, the browser will remember which cert to use.

                  • Remember what I had selected in the DOM for a limited time waiting for asynchronous DOM updates

                    When I debug a page that loads most of the content async, I would like a way to keep the selected DOM element until the async request is loading. This means that I don't have to traverse the tree every time to find the element I'm currently working on.

                            - If a JavaScript file containing syntax errors is opened in the debugger the syntax error will have a red squiggle and there will be a warning glyph in the gutter

                                • Edit and Continue

                                  This feature would add the ability to edit JavaScript code when stopped in the debugger then to continue (or step) and execute the modified code.

                                  Proposed Design
                                  - Will have a number of limitations (e.g. not applicable to eval code)
                                  - Will not modify the state of the DOM/Objects/Closures etc.

                                    We’ve started work on edit and continue in the F12 debugger. It’s going to take us a while as it’s a complex feature with many moving parts. The first part we’ll tackle is applying changes when you’re not at a breakpoint. So you could do something such as editing an event listener then trigger the event again. No dates for when, or if, we’ll be able to deliver it.

                                      • Canvas2D text decoration

                                        Add a textDecoration attribute to canvas 2D contexts, behavior similar to existing "font" attribute: It's a DOMString, parsed the same way as corresponding CSS property (text-decoration).

                                        • Force Active and Focus Pseudo States

                                          This feature would add the ability to set the focus and active pseudo states from the DOM Explorer pseudo state checkboxes.

                                          Proposed Design
                                          - New checkboxes on the pseudo state toggles
                                          - Would not fire any JavaScript events (e.g. focus, blur)
                                          - Force on only no force off (off toggle state will follow browser default)
