All the other apps in Office 365 work as normal but when I launch Sharepoint in a normal Firefox window I get the following error message:

  • Sorry, something went wrong
  • An error has occurred on the server.
  • Technical Details
  • Troubleshoot issues with Microsoft SharePoint Foundation.
  • Correlation ID: xxxxxxxxxxxxxxxxxxxxxxxxxxxx
  • Date and Time: xxxxxxxxxxxxxxxxx

Firefox is up to date (v81.0) and running on a modern up to date Win 10 Pro laptop, I've cleared all my browser history and rebooted but without success. The same web page works without problem in Edge and Chrome but in Firefox it will only work in a private window.
