How can I change my Google Chrome/Chromium-based web-browsers to open the old certificate viewer, the one built-in to Microsoft Windows instead of the "new" Chromium one?

Old (goal) Windows Certificate Viewer:

Windows Certificate Viewer


New (currently) Chrome Certificate Viewer:

Chrome Certificate Viewer


What I've tried

  • I tried setting the chrome flag chrome://flags/#chrome-root-store-enabled to disabled and enabled but it didn't change the viewer.
  • I couldn't even find the technical terms for both of these viewers in a web search or on Stack Exchange

See here for the reasoning behind the new certificate viewer: https://chromium.googlesource.com/chromium/src/+/main/net/data/ssl/chrome_root_store/faq.md

In Chrome 105, Chrome on Windows and macOS transitioned from using the native platform certificate viewer to the Chrome Certificate Viewer. This transition promotes a consistent experience across platforms as we begin the rollout of the Chrome Root Store.

It is the same now in all Chromium-based browsers.

  • Thanks for linking me to a official article, now I know at least how to search. So it seems like there is no (longterm) "workaround"/setting to change back to the old/Windows Certificate Viewer. Which makes sense when the trust/root store is built-in to chromiums. At least now I know that.

    Thanks again, Google. Now I have no way to check why (and which cert in a chain) is actually invalid and have to export it to my PC to check that natively...
