Importing old firefox stored passwords to new account

Hi folks, I'm having trouble with importing old firefox stored passwords to new account. I got all the old data (logins.json, key3, key4,...)

I tried copying the logins.json and key3/key4.dbf file into the firebird profile root directory but they dont seem to load. It doesn't show anything no matter if I'm logged into a firebird account or not.

Since the old files are only a week old I'm guessing I shouldn't need to convert files.

When I convert logins.json file to csv I see the info is there.

What's the catch?

First; open your file browser to the New profile;

Type about:support<enter> in the address box.

Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

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

Linux: Under the page logo on the left side, you will see Application Basics. Under this find Profile Directory. To its right press the button Open Directory.


Second, open another file browser to the Old profile. You should see it on the directory "tree" in the first file browser. Right-click on that folder and select Open In New Window.


Warning ! ! Only Copy the files you are told. We will avoid anything that might cause problems. Here is the list of files;

logins.json and key3.db [v58+]key4.db : These are the password files. Copy Both !

I always close Firefox before copying the files from the old profile.
