Firefox passwords lost following a Reset

Hello, Firefox has 'lost' my passwords following a reset. The reset was 'recomended' by FF because it was slow starting. I use a master password on the passwords file.

I've tried to follow some standard solutions to the problem but: 1) There is no "Old Firefox" folder - neither on my desktop, nor elsewhere.

2) Either FF did not create a new profile, or it replaced the old one. Given the age of the timestamps in the folder, I think it did not create a new folder.

I have, manually, created a new profile folder.

3) I have found 'key3.db'. 'key4.db' and 'logins.json', and copied them to my new profile folder.

logins.json seems to contain old pasword info, but the info encrypted. New passwords appear to be added to the file as usual and displayed, but old ones are not being displayed or used.


OS: Windows 7 I also have FF Developer Edition installed.

That was very good work. Well done.

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.
