Where have my logins gone?
I 'refreshed' firefox as suggested. The guidance suggested that all my logins and passwords would be preserved but when I check the Logins and Passwords all have been cleared. I am now faced with the arduous task of resetting many many login credential. Poor advice from Mozilla.
You copy the two logins.json and key4.db files from the "Old Firefox Data" folder on the desktop to the current profile folder with Firefox closed to replace the current files. This means that you lose passwords you already saved in this profile, so make a note and make sure to keep a backup of the current files in case you need to access the old password files.Lire cette réponse dans son contexte 👍 1

Sorry that happened to you.
Did an Old Firefox Data folder appear on your Windows 10 Desktop screen?
It should be there as long the Refresh process was allowed to run until is was completed and you waited until Firefox told you that the process was completed.
Also, is any other data missing from Firefox after the Refresh?
Yes, I do have that file on my desktop. Please let me know how I can restore my login and pwd data from this file.
I don't appear to have anything else missing.
when you use the refresh feature in Firefox then a new profile is created and some personal data (bookmarks and history, Form Data, tabs) is automatically imported. The current Firefox profile folder will be moved to an "Old Firefox Data" folder on the desktop. Installed extensions and other customizations (toolbars, prefs) that you have made are lost and need to be redone.
It is possible to recover data from the "Old Firefox Data" folder on the desktop, but be cautious not to copy corrupted files to avoid carrying over problems.
You can copy logins.json and key4.db with Firefox closed to the current profile folder to recover the logins.
You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
- Help -> Troubleshooting Information -> Profile Folder/Directory:
Windows: Open Folder; Linux: Open Directory; Mac: Show in Finder
- bookmarks and history: places.sqlite
- favicons: favicons.sqlite
- bookmark backups: compressed .jsonlz4 JSON backups in the bookmarkbackups folder
- cookies.sqlite for the Cookies
- formhistory.sqlite for saved autocomplete Form Data
- logins.json (passwords) and key4.db (58+) or key3.db (57 and older) (decryption key) for Passwords saved in the Password Manager
if you only have key3.db then make sure to remove an existing key4.db
- cert9.db (58+) or cert8.db (57 and older) for (intermediate) certificates stored in the Certificate Manager
if you only have cert8.db then make sure to remove an existing cert9.db
- persdict.dat for words you added to the spelling checker dictionary
- permissions.sqlite for Permissions and possibly content-prefs.sqlite for other website specific data (Site Preferences)
- sessionstore.jsonlz4 for open tabs and pinned tabs (see also the sessionstore-backups folder)
I have a Mac using Version 79. I, too, was misled by the 'REFRESH' option to correct my slow browser. I see the key4db. I see 2 versions from when I refreshed this morning and 2 from 2019. Am I understanding correctly, I must physically remove the current key4db somewhere and replace it with the key4db from the 'old Firefox folder' that has today's date on it? Can you indicate the pathway for me.
Please revise the refresh instructions, or correct the password/login info deletion from a refresh. This is very inconvenient and frustrating for non-techs.
The key4.db (previously key3.db) is the key file that stores the encryption key and the additional master password. The actual logins are stored in logins.json and the two files logins.json and key4.db need to match to be able to decrypt the logins stored in logins.json. The logins.json file is a plain text file and you can check its content in a text editor.
So, after refreshing, I have the Old Firefox Data folder on my desktop. How do I restore the missing passwords and login info? Open the logins.json file and copy the contents that are presumably the login and password info into where, on my Mac?

Thanks - I followed the process you outlined above and works perfectly - I now have all my logins and password restored. Thanks
