You need to enable import CSV in the Password Manager (about:logins) via the about:config page temporarily as this menu item is currently hidden for performance reasons that you can experience if you import a large amount of logins.

• about:config => signon.management.page.fileImport.enabled = true
• https://support.mozilla.org/en-US/kb/about-config-editor-firefox

After you enable the menu item using the method described by cor-el, I'm curious whether Firefox understands the Keeper file or whether it only understands its own exported CSV files. Let us know what happens.

You asked: "After you enable the menu item using the method described by cor-el, I'm curious whether Firefox understands the Keeper file or whether it only understands its own exported CSV files. Let us know what happens."

The Keeper created CSV file had four columns with no headers. The first column was blank and I deleted it. the 2nd, 3rd, 4th columns were in the correct order but to be safe, I added a first line row with headers in case Firefox needed to read the actual header name

As far as enabling "import CSV in the Password Manager (about:logins) via the about:config page" there are two signon lines. I had already turned the second line (enabled preference) to "true" but not the first line (enabled).

about:config => signon.management.page.fileImport.enabled = true signon.management.page.fileImport.enabled preference = true

After following your instructions and tweaking the CSV file, the import worked perfectly. Thank you so very much for your help.

Jscher asked "After you enable the menu item using the method described by cor-el, I'm curious whether Firefox understands the Keeper file or whether it only understands its own exported CSV files. Let us know what happens." see my earlier reply.

FYI - The reason I bought and tried KEEPER is that more experienced users than I have made statements about browser (like Firefox) saved passwords. A few examples are:

"You should not use your browser to save passwords. Browser stores are not secure unless you use a master password ... Get yourself a password manager (free or paid) that is portable

"You ... (have) to trust the password manager vendor. Choose carefully. I don’t worry too much about my password managers tracking me, but I do worry about security vulnerabilities in the password managers.

"Common advice is to NOT use the password manager included with the browser. My preference is for standalone password managers.

Having said that, what has or can Firefox do to ensure the browser saved passwords are (1) SAFE, (2) cannot be Hacked, (3) security vulnerabilities in the password managers are fixed ASAP. Your assurance that Firefox is as safe or safer than Keeper and similar managers would really increase my confidence in Firefox

Thanks again for all of your help

You need to set a Primary Password and make it difficult to guess (but easy for you to remember). I'm sure if anyone reports a vulnerability, Mozilla would want to fix it promptly.

Use a Primary Password to protect stored logins and passwords

Two pieces of info googlers may find helpful:

The second one is not legit/doesn't get used - it looks like someone misread someone's instructions and added preference to the name of the real setting.

This is bad advice. (The bold part is good, the italics part is largely wrong and the plain part is weak.) I see the advice source is here. And that post in turn relies on the MISLEADINGLY titled RedLine malware shows why passwords shouldn't be saved in browsers which actually shows why passwords shouldn't be saved in Chromium-based browsers (Google Chrome, Edge, Opera, Whale) whether on PC, Mac, or Linux. Which shows why jscher2000's advice is good. (No surprise, as he's a Top 10 Contributor!)

Primary Password is the term Firefox/mozilla now use instead of the non-PC "Master Password".

PS The "reason" this feature is hidden by a setting is that Firefox slows down for a little while when extremely large password files are imported, which could surprise users. It seems an odd judgement call to me that Tim Giles is holding back turning this setting on by default even though the main performance problem has been solved that was holding it back. Because the main performance problem has been solved, https://bugzilla.mozilla.org/show_bug.cgi?id=1705529 is not really a blocker, but is treated as one. I think the hope is to draw a new mozilla developer into the fold. Might work.

As a footnote to this older thread:

Import broke in Firefox 104 or 105 due to disabling an insecure script method used in the import. The code for this feature has been rewritten in Firefox 108 -- currently in beta testing, scheduled to release on December 13, 2022 -- and once again works there after enabling the menu item.
