Major Windows 10 updates may give you choices about what to do with your data, such as, leave it in place, back it up, or dump it. The back it up option creates a temporary folder (saved for 28 days) under

C:\Windows.old

Can you find such a folder on your system?

If so:

Before proceeding, please set Windows to show you hidden files and folders: https://support.microsoft.com/en-us/help/14201/windows-show-hidden-files

Then check here:

  • C:\Windows.old\Users\<username>\AppData\Roaming\Mozilla\Firefox\Profiles\
  • C:\Windows.old\Users\<username>\AppData\Roaming\Thunderbird

If you find recent data there, please pause and we can suggest how to resurrect your saved files.
