Hello, All of my saved logins and passwords disappeared just two days before. When I open the firefox>xxx.default directory, I could see logins.json.corrupt and logins.json-1.corrupt.

If you could please let me know how to recover my logins and passwords, I would highly appreciate it.

Do you see logins in either of theses files ?

logins.json is a plain text file in JSON format ({"key":"value"} pairs), so you can inspect the file in a plain text editor or open the file in a Firefox tab. If you give the file a .json file extension then Firefox will use the JSON viewer, so you can test the validity of its content. If you see nothing wrong with the content of one of the files then try to use this copy in place of the current logins.json.

Make sure to keep a backup copy of both logins.json.corrupt files and replace the current logins.json file with one of the corrupt files (current logins.json is probably empty) to see whether that restores the logins.

Make sure that Firefox is closed when you replace files.

No. The logins.json file has the new details I started saving from yesterday and the other *.corrupt files are empty. One of the corrupt files is dated 21/01/2020, so something must have happened during that time. Is there any other place I can restore these login data?

Getting access to the lost passwords would require a backup of at least logins.json and possibly a matching key4.db key file if you made changes to the master password. This backup can be a backup you made in the past or a profile stored in the "Old Firefox Data" folder on the desktop if you ever have used the refresh feature in Firefox or possibly on a synced device if you ever have synced passwords.
