All stored passwords/logins on my firefox are now gone. I noticed in the user profile area there is a file called logins.json.corrupt which I'm guessing is the problem. Is there any way to recover all my lost passwords? Running Firefox version 45

Hi.... Please backup your files even the corrupt on to another location just in case please. You can give this a try: The Remember Passwords extension is one possibility. You can force Firefox to re-import your old passwords. Here's how: 1. In the location bar, type "about:config" (without the quotes) and press <Enter>. 2. Click [I'll be careful, I Promise!] 3. Search for the preference: signon.importedFromSqlite 4. Right click on signon.importedFromSqlite, and select "Reset". 5. Go to Help-->Troubleshooting_Information, then click on [Open Folder]. That will open Windows Explorer in your Firefox profile. 6. Close Firefox 7. In your profile folder, delete the file "logins.json". The next time you start Firefox, it should re-import your passwords from your old passwords file. If this does not work please replace the corrupt file back and someone will get back to you, G'luck

You can check in Windows Explorer if there is a previous version of the logins.json and key3.db files available.
