Hello jjj123,

As your system details show that you are on Mac OS - would you please take a look at this thread :

That thread shows another person who seems to be having the same problem as me, but offers no solution to it as far as I can tell

You're right; same problem and no solution from me, only the advice to give bug reports a vote .....

But maybe cor-el's post in that thread might work for you ?

As per cor-el's post, I was able to export my Chrome passwords as a .csv file, and then convert the CSV text to JSON text via https://www.dgendill.com/content/csv-to-json-converter/ But I can't figure out how to then import that JSON text as passwords.

I suggested a possible solution in this thread that involves a few steps.

1. export the logins in Google Chrome to a CSV file.
2. modify the header line to the field names Firefox expects
3. convert the modified CSV file to JSON
4. import the logins in this JSON file via the Browser Console.

Firefox expects these field names in the JSON file, so if the CSV file uses different field names then you need to modify the first line in the Google Chrome CSV file.

• [{"username":"xxx","password":"xxx","hostname":"https://"}]';

For step 3 you can use an offline converter (works locally):

• https://www.dgendill.com/content/csv-to-json-converter/
• https://www.convertcsv.com/json-to-csv.htm

For step 4 you can use the code posted below in the Browser Console. You first need to enable the command line in the Browser Console to be able to paste the code.

• https://developer.mozilla.org/en-US/Tools/Browser_Console

The JSON file should have this format: array of JSON login records separated by commas [{login1},{login2}] with at least username and password and hostname key:value pair.

• [{"username":"xxx","password":"xxx","hostname":"https://"},{more-logins}]

/* export logins as JSON format */
var lg = prompt("Logins",JSON.stringify(Services.logins.getAllLogins()));

/* import logins in JSON format */
var lg;
if (lg = prompt("Array of Logins in JSON format: [{login1},{login2}]",lg||"?")){
try {
lg = JSON.parse(lg);
try {/*[60+]*/
 var i,LG;
 for (i=0; LG=lg[i]; i++){if (!LG.origin){LG.origin = LG.hostname}}
 ChromeUtils.import("resource://gre/modules/LoginHelper.jsm");
 LoginHelper.maybeImportLogins(lg);
} catch(e) {/*[42-59]*/
 Components.utils.import("resource://gre/modules/LoginHelper.jsm");
 var i;
 for (i in lg) LoginHelper.maybeImportLogin(lg[i]);
}
} catch(e){console.log(e);}
}
