My guess is that Firefox accidentally created a new profile for you and set that as the default. We've seen that issue recently because Firefox recently changed how it handles profiles.

Usually, fixing this is pretty easy. Just type about:profiles in the Firefox address bar. This will load a list of profiles on your computer. Press Launch profile in new browser on whatever profile is not in use. If it has the data you are looking for in it, just select Set as default.

There have also been some cases of Firefox using a separate profile when you use it to open a link from another program (for example, if you click a link in the Thunderbird email program). In this case, it's the same steps.

Hope this helps.

On both of our computers it only has the new profile. What is the next step

What security software do you have?

There have been reports that AVG/Avast is causing issues with passwords disappearing.

You can check the profile folder to see if there are logins.json.corrupt files present. If you find such a file then try to rename logins.json.corrupt to logins.json.

• keep a backup copy of all logins.json files

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.

  Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder

YES!! I do have AVG and that did the trick. I get a NOT RESPONDING for a few seconds but at least I have all my passwords back.

THANK YOU!!

You're welcome and thanks for reporting back that this helped.

Hi I have a similar problem:

yesterday, I uploaded to the last version 69.0.3 64bit.

Today when I've tried to enter on Facebook, all my passwords for Facebook, at least, have gone. I had like 3 other accounts for gaming, but all the passwords and usernames disappeared. There was no logins.json.corrupt file in the profiles folder, and I've tried to open the other profiles from about:profiles, but no useful results. The major problem is that to recover facebook passwords they ask more than just the e-mail, you must also ask 3-4 people selected by then to help you reset, and since the profiles were for gaming only, I know no one....
