    • I’m also not seeing progress events for file uploads, they only seem by be called at the end of the XHR request…

    • Hello,

      Thank you for providing this information about the issue. We are pleased to report this feature is fixed in Edge 16199 and is available in our latest Insider Preview build.

      Best Wishes,
      The MS Edge Team

    • I updated to Edge 41.16199.1000.0/EdgeHTML 15.16199 and the Progress Event still is NOT fired. You can reproduce it with uploading a big file here:

    • Hello,

      Thank you for providing this information about the issue. After thorough testing, we are unable to reproduce this problem in Edge 16195-16220. We can see the issue in Edge 15, but it appears to have been fixed in 16.

      Please try the repro again and if it still does not show the progress, run dxdiag (Windows key + r and type dxdiag, enter, then click Save all Information) and attach the txt file. Additionally, a screenshot of the upload in action may help us identify a difference between our repros.

      Best Wishes,

    • I’m using Microsoft Edge 41.16215.1000.0 / Microsoft EdgeHTML 15.16215 which is included in the latest Insider Preview.

      Is there a way to update EgdeHTML 15.x to EgdeHTML 16.x?

    • Hello,

      Looks like we are still calling 16215 part of 15.x, so 15.16215 is the latest. I am unable to repro the problem in 15.16195 through 15.16220.

    • Hi,
      if you upload any file with this example, the “onprogress” Event still is only fired once: at 100%

      You can download the DxDiag here:

      Best Regards,

    • Hello,

      Thank you for the new repro sample. We see the problem and are investigating.

    • I have been experiencing the issue with Microsoft EdgeHTML 15.15063.
      OnProgress event is fires only once - after the whole portion of data has been transferred.

    • Yes I am having the issue as well as lots of customers using edge. EdgeHtml: 15.15063 Edge: 40.15063.0.0

    • When?

      Any information about patch release?

    • Still having this with the fall creator update:
      Edge: 41.16299.15.0
      Edgehtml: 16.16299

    • I’m having this issue as well.

    • Issue still happening on latest Edge (16).

    • This issue affects CKEditor 5 too: https://github.com/ckeditor/ckeditor5-upload/issues/79

    • Not working in 17.17074

    • Can also confirm it’s not working in Edge 41.16299.15.0
      I hope this can be fixed soon, a lot of people are using Edge & we get complaints about it.

      Changed Steps to Reproduce

    • Just ran into this myself. I was pulling my hair out for a good hour, thinking I was doing something wrong.

    • Still a problem in Microsoft Edge 41.16299.248.0 / Microsoft EdgeHTML 16.16299

    • Same here. I’m using the following to build an xhr for $.ajax:

      var xhr = new window.XMLHttpRequest();
      function on_progress(evt) {
        if (evt.lengthComputable) {  
          var percentComplete = evt.loaded / evt.total;
          progressbar_set_value(progressbar_, percentComplete)
          //Do something with upload progress
          console.log("XMLHttpRequest.upload progress", percentComplete)
      //Upload progress
      xhr.upload.addEventListener("progress", on_progress, false); 
      //Download progress (do we ever use this?)
      xhr.addEventListener("progress", on_progress, false); 

      Works fine in chrome and firefox, but in edge only the final event “XMLHttpRequest.upload progress 1” is fired.

    • @Scott: thanks in advance for solving the problem. It was frustrating to find a solution for Edge, without success. Please make a hotfix asap.

    • Thank you everyone for reporting this issue and for your patience. I’m happy to report that this issue has been fixed and will be available in an upcoming Windows insider preview build.

    • Could anybody confirm when the fix for this issue is likely to be released ?

      I’m also having the issue with my edge :(

    • I’m very interested too when the fix will be released.

    • VERY VERY interested WHEN the bug will be fixed!!!

    • Microsoft Edge 42.17134.1.0
      Microsoft EdgeHTML 17.17134

      The problem is still present

    • I can see this wrong behavior also in:
      Microsoft Edge 42.17134.1.0
      Microsoft EdgeHTML 17.17134

      Available in the lates Win10 + Edge image from https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/

    • It worked fine with the Edge available in the VM with Windows 10 (Build 10586.1176) and MS Edge (version 25.10586.672.0)

    • @Oscar: where did you get MS Edge in Version 25.10586.672.0? Here https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/ is only version 17.17134 available. Where to test the the MS Edge (version 25.10586.672.0)? Thanks.

    • @Krzysztof: It was an old image available in the VMs site. Downloaded it on March 2016 if I’m not wrong. I probably can provide the VirtualBox .ova file if needed.
      Here an screenshot of the About info in MS Edge

    • @Oscar: thank you, this is a old version from 2016:
      Microsoft Edge 25.10586.672.0
      Microsoft EdgeHTML 13.10586

      The latest version of MS Edge is:
      Microsoft Edge 42.17134.1.0
      Microsoft EdgeHTML 17.17134

      And the new release with the fixed bug should be:
      Microsoft Edge ???
      Microsoft EdgeHTML 18.18218

      You tested with old version from 2016 and it is not relevant.

      @Everybody and @MicrosoftTeam: when will the fix be available and in which version of Windows can the fix be tested? Urgent!

    • @Krzysztof: Yes, I knew I was testing it with a super old version. I just wanted to point out a version where it worked as expected so the guys at Microsoft Team could take a look and check what they changed to make it fail.

    • The issue was declared as FIXED and available in version 18.18218.

      @Everybody and @MicrosoftTeam: when will the fix be available and in which version of Windows can the fix be tested? Urgent!

    • This issue is still present.

      • sigh *
    • I just got the October update for Windows which updated Edge. That fixed this bug.
