Aurora updated to 35.0a2 (x86 en-US) and I lost all the passwords in Save Password Editor

Question

The computer is used for my office and Mozilla was set to automatically update. Prior to the update earlier today, I looked into Save Password Editor 2.8.1. Later, after Aurora updated to 35.0a2, the add on (Save Password Editor) did not exist. I downloaded the add-on again and it is empty (as I thought it would be). Can I still access the passwords? They are on a computer that was used by my now deceased business partner. I was going to restore the computer to a previous date (earlier than today) but this computer was not set up for a system restore. Any help to either revert to an earlier Aurora edition or to access the passwords would be greatly appreciated!!

You need to recover the logins.json (or possibly signons.sqlite) and key3.db files to restore the passwords.
*C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\
The "AppData" folder in Windows Vista and later Window 7+ versions and the "Application Data" folder in XP/Win2K are hidden folders.

*http://kb.mozillazine.org/Profile_folder_-_Firefox
Firefox 32 and later builds store the passwords in the logins.json file in the profile folder and no longer use the signons.sqlite file that has been used before (the matching key3.db file is still needed).
If you still have the signons.sqlite file used in previous Firefox versions then you can try to force Firefox to migrate the passwords saved in that file (you will lose passwords saved in Firefox 32+ versions).
You can force Firefox to reimport the passwords from the signons.sqlite file and rebuild the logins.json file with these steps:
* reset the <b>signon.importedFromSqlite</b> pref on the <b>about:config</b> page to the default value via the right-click context menu
* delete the <b>logins.json</b> file in the Firefox profile folder with Firefox closed
When you restart Firefox then you should have the signon.importedFromSqlite pref with the value set to true and you should have the passwords imported in the Password Manager unless there may have been errors.
