Steps to reproduce


  1. Install OneNote Web Clipper from Windows Store;
  2. Open any HTTPS-enabled website, e.g.,;
  3. Press F12 to open dev tools, go to Console tab;
  4. Right-click the page, then click ‘OneNote Web Clipper’ context menu item;
  5. Observe the console.


The console is populated with a lot of SEC7111: HTTPS security is compromised by …

Expected Behaviour

Since the user is in control of the extensions, and ms-browser-extension does not initiate unsecure transfer over network, HTTPS security should not be thought to be compromised by ms-browser-extension protocol.

But if the extension accesses network resources, the check should be done accordingly.

    • I also experience SEC7111 warnings in F12 console.
      I use Microsoft Edge 38.14393.0.0 / EdgeHTML 14.14393
      I have only ‘Office Online’ extension installed.
      Entering for example this site:
      no one of embedded YouTube videos is visible.

    • Thanks for filing this bug! We’ve seen this bug internally as well, and it is a result of our developer tools displaying an error when they shouldn’t be. The underlying functionality works as expected (i.e. the extension checks when it has to and ignores extension-served resources on HTTPS sites under the hood), but the dev tools will still display errors regardless. We’ll address this in a future update, but hopefully this clarifies the issue a little.

      If you’re seeing a case where extension-served resources are actually blocked, please let us know and we will investigate further.
