Lost passwords

I have a 2015 Dell alien using Microsoft 8 and have been very happy with it. Recently my PC had a problem and went into a "self repair mode". This has happened before with excellent results. This time some things are missing. Most noticeably all my Firefox stored passwords. I really depend on that wonderful service you created as I am in my 70s and cannot keep all those passwords straight.

My question, after all that, is can my passwords be retrieved? Does Firefox use a cloud to retrieve passwords in case of something like this? Please save me hours of work and worry.

Firefox has been my go-to since I herd about it several years ago on NPR radio

thank you MaryJane Smith ...

Unless you are using sync, your data stays on your system.

What about the rest of your profile? Settings, bookmarks, history, passwords . . . .


Before doing anything, I suggest; Perform a System File Check to fix corrupted system files

Firefox 80+ has a logins-backup.json file in the profile folder that can be used in case of issues with logins.json or to undo an accidental delete of a login, so you can check if you can find this file in the profile folder or in a backup and replace the current logins.json. Make sure to keep a backup copy of all involved files (logins.json and key4.db and logins-backup.json)

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.

If you use a Primary Password then you can prevent losing passwords by canceling the PP prompt. You need to logout beforehand by canceling a PP prompt, e.g. by clicking the eye icon in Lockwise (about:logins).
