Hi Ellie, if you deleted it from the about:profiles page, unfortunately, Firefox does not use the Windows Recycle bin for that delete, it's permanent. Do you have any recent backups of your computer? ''If not:'' Windows itself may have captured a copy of your profile folder when it updated itself. This is called a shadow copy, and you can explore for one using either of the following tools. They unfortunately do not seem to always recover readable files, but you certainly can give it a try: (1) Set Windows to show hidden files and folders, if you haven't done this before: https://support.microsoft.com/en-us/windows/view-hidden-files-and-folders-in-windows-97fbc472-c603-9d90-91d0-1166d1d9f4b5 (2) Download and install one of the following programs: * ShadowExplorer: http://www.shadowexplorer.com/ * Shadow Copy View: https://www.nirsoft.net/utils/shadow_copy_view.html (3) Start up the program and look for the latest restore point. Then explore along this path to see whether you can find a shadow copy of your profile (most likely default-release?): \Users\''your-user-name''\AppData\'''Roaming'''\Mozilla\Firefox\Profiles\''your.profile'' (4) I don't know whether you can export out the entire folder, or need to export individual files. Either way, create a folder on your Desktop/Documents/Downloads for easy access.
