Hey Vince, I am sorry to hear that logins have disappeared after a crash! That is not supposed to happen. There are two things I would like you to look for please before we give up. Please check the profile folder to see if there are multiple profiles for Firefox. First, go to this setting, as the preferences menu has changed # Go to about:preferences#privacy # Next to "Remember logins and passwords for websites" click on "Saved Logins..." #Are they there? Find the Profile Folder with this [ [[Profiles - Where Firefox stores your bookmarks, passwords, and other user data]] ] or go to about:support and click on the button next to Profile Folder. You are going to want to look for this file in the profile folder: *logins.json Is there a file with a recent timestamp? Copy it over into the profile folder that opened up originally. Then restart Firefox. That should restore another version and a least recover a few of them. What did you find?
