      open -a "Google Chrome" --args --unsafely-treat-insecure-origin-as-secure="http://scratchx.org/" --user-data-dir
      

      

    • Untested: If you are on windows, use the following command in command prompt:

      chrome.exe --unsafely-treat-insecure-origin-as-secure="http://scratchx.org/" --user-data-dir
