Came back from Thanksgiving weekend and everything is wiped. I have looked and not found any solution for Firefox70. When I started trying to go to my usual sites, everything was lost. It doesn't show the saved username or anything.

In the event that the passwords information is lost, you should record all information in a separate text file somewhere else on your hard drive, or written down. You can easily copy and paste if you need to do so. If you are concerned about someone else looking at that file, you can compress it using a password.


Look on your desktop. Do you see a folder called; Old Firefox? Look inside. Look for the folder with the latest creation date.

I went to that page, it shows: signon.autofillForms : True signon.autofillForms.autocompleteOff : True signon.autofillForms.http : False

So what does that mean for recovering all of my passwords?

I don't have a folder called "Old Firefox"

If you lost personal data then it is possible that a new default-release profile folder has been created. See "Determine if Firefox has created a new profile":

You can open the about:profiles page via the location bar to check whether multiple profiles are present and what profile Firefox currently is using.

It appears I am using the default profile and it is the only profile that exists.

Hi dr, just try this...

   Open the Firefox web browser.
   Load about:support.
   Click on the "open folder" link near the top of the page that opens; this opens the profile folder.
   Close Firefox.
   Check if you see a file called logins.json.corrupt.
   If you do, rename the file to logins.json to fix it.
   Start Firefox. The passwords should be available again.

I did that fix a few months ago, and it seemed to work. I currently have: logins.json logins.json.before-recovery logins.json.corrupt logins.json.old logins.json-1.corrupt

So what do I need to fix/replace/ get rid of?

You can check the file dates and file size of each of the logins.json file and possibly check the content by opening the file in a Firefox tab.

You can also try this extension that was meant to be used in cases like this where logins.json is corrupted.

The most current logins.json shows that it's only 4KB and was updated yesterday. However, there is a logins.json.corrupt that is 68KB from a few months ago. Should I go ahead and rename the 68KB corrupt one. It seems that will reset me to a few months ago at least
