I'm trying to migrate my Firefox application and all of its associated data from my old computer (Windows 7) to my new computer (Windows 10). I copied my Mozilla folder from my old computer onto a flash drive. Then on my new computer, I executed the application from the flash drive, but it doesn't have my associated data from my old computer. What should I have done?

Hmm, which Mozilla folder? It needs to be from this hidden folder path:

C:\Users\<username>\AppData\Roaming\Mozilla\Firefox

To set Windows to show all hidden files and folders, see: https://support.microsoft.com/en-us/windows/show-hidden-files-0320fe58-0117-fd59-6851-9b7f9840fdb2

To get that set up on your new computer:

Could you try the transplant method described in the following thread -- note that your source folder will be your flash drive instead of a C:\Windows.old folder:

Note that you need to register a profile in profiles.ini to make Firefox recognize this profile.

You can find the profiles.ini file in a hidden location:

  • Windows: %AppData%\Mozilla\Firefox\
    C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\
  • Mac: ~/Library/Application Support/Firefox/
  • Linux: ~/.mozilla/firefox/

You can recover an unregistered profile via these steps:

See "Profile was moved or renamed":

Note you should never use "Choose Folder" to specify a folder that already contains files and that isn't a Firefox profile folder. Only use "Choose Folder" to recover an profile that isn't listed in the Profile Manager.
