How its possible that I lost all saved passwords in website?
Today I noted that all my passwords saved in Mozilla disappeared. I didn`t clear any information from Browser using "clear history". No one use my laptop. How it's possible?
If you have sync, and there is a problem anywhere, Shut Down Sync Immediately On All Devices to prevent the problem from spreading. Once the problem is fixed, perform the same repair on all computers/profiles before using sync again.
What about the rest of your profile? Bookmarks, settings, toolbars?
Look on your desktop. Do you see a folder called; Old Firefox? Look inside. Look for the folder with the latest creation date.
You would need older backup copies of logins.json and key4.db to recover the lost passwords.
You can look at this utility to browse System Restore points.
- System Restore Explorer
Did you already reboot the computer?
You can also check for orphaned profiles that aren't listed in the Profile Manager and on the about:profiles page (profiles.ini).
