I was on a website and noticed I was signed out, so I went to log in, but the browser did not display the username/password like it usually does. I clicked on the hamburger menu to go to my passwords and I noticed that it said "Account disconnected" at the top. I figured this was the issue, so I clicked it to log in. After going through the forgot password steps, I got logged in to Mozilla. Firefox then prompted me if I wanted to save that password and I clicked yes. I then went to the password manager and the only one listed was the Mozilla password that I just saved. After some digging, I found there was a logins.json.corrupt file in the profile folder. I tried renaming it to logins.json but that does not work. I tried viewing the corrupt file, but it was not legible.

Is there any way to recover the passwords or are they gone for good?
