How can I export my passwords from firefox sync (not regular firefox) to my computer? This is on quantum

I had lost my passwords, and had all my bookmarks on both firefox quantum, and with developer edition. Even though I think i was signed into sync, I could not get my information back. I had done no changes to my computer, and it appears this happened from an update. After searching online, I was able to get my passwords to show synch using developer edition. I am afraid to keep the passwords only using sync, as I am thinking this may happen again... I would like to have a backup file that works, so I can setup an older firefox for events in the future, with my passwords. Please let me know how to export the passwords, or bring back an option for export. If this is not possible, I may not use firefox anymore... I have been using firefox for years, and always have recommended to other people. However, I like the original firefox the best. I do not need a browser which reminds me of chrome or windows. Thank you

If you have sync, and there is a problem anywhere, Shut Down Sync Immediately On All Devices to prevent the problem from spreading. Once the problem is fixed, perform the same repair on all computers/profiles before using sync again.


Is there a computer that the password files intact? If so, Copy the files to a thumb drive. After, Copy it to the other computers/profiles (overwrite the current files).

key3.db and logins.json : These are the Password files. Copy Both !


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

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.

With sync turned off, which it was already under regular firefox, not developer mode... I replaced the files as requested. Unfortunately, there was no key3.db .... however there was key4.db. I copied and renamed that to key3, and replaced the logins file. Upon rebooting firefox, the issue was no resolved. Any other suggestions?

I did a web search. The key4.db file is not a Firefox file.

If you can't find key3.db and logins.json together, the data may be lost.


Look on your desktop. Do you see a folder called; Old Firefox?
