How do I merge saved logins data from to installations of firefox?
Hello,
I have two PCs running Firefox where I save passwords for website logins. Some of the passwords change because of expiration requirements and over time the data on the two PCs diverge. How do I merge the save password information. Resolution of duplicate entries would be nice to have, but a simple merge would be a good start.
Thanks in advance for any help.

This will take some thinking. Are all the computers using Firefox? Is this something like home/work/personal . . . . .
Do Not Use Sync ! ! This could merge the data the wrong way.
For now, save the current passwords using;

CSV: https://support.mozilla.org/questions/1253828 (copy/paste from console)
Go thru those lists and cross out any data not current.

Thanks for the reply. To answer your question, the two PCs are running Firefox. Otherwise, I could have used the import function.
Also, how do you import the data exported out of Firefox (into a CSV or json file ) as you suggested into the database?
Thanks!

Make sure to keep a backup of all involved files from both Firefox versions before proceeding.
- logins.json and key4.db
You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder - https://support.mozilla.org/en-US/kb/Profiles
See this reply for possible alternatives using the Browser Console to run JavaScript code to export logins to JSON and import this flie.

Creating the password list as I suggested gives you a printed backup.
Thank you! I take it the suggestion is to manually enter them by referring to the printed list.

Thanks! Sorry, but this doesn't address my original question of merging the two sets of data.
The reply I posted above has two sets of JavaScript code, one to export and another to import logins. It should be possible to export the logins in one installation to a JSON backup using code in the Browser Console in the thread I posted above. Then you can import this JSON file in the other Firefox instance with the import code in that same reply. The export and import are done asynchronously, so it can take a few seconds before you see the imported logins. That should merge the passwords without getting duplicates (the import code skips logins that already exist).
