Password transfer from another firefox profile
My old computer crashed. I have the hard-drive in an external case and have it connected to my new computer. I installed firefox on my new computer, but I can't figure out how to get the passwords from the previous profile to my new profile. I have located the files on the old hard drive, but import will not work. Is there anything I can do?

You need to copy logins.json and #key4.db from the profile on the USB drive to the current profile folder. You can only import a logins CSV file if you previously created such a backup.
You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page (Root directory).
- Help -> More Troubleshooting Information -> Profile Folder/Directory:
Windows: Open Folder; Linux: Open Directory; Mac: Show in Finder - https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data
You can copy certain files with Firefox closed from one profile folder to another profile folder to transfer personal data. Note that best is to avoid restoring a full profile folder and only restore important files that are safe to restore/transfer.
