Only the Lockwise App for a mobile device uses a Sync account to store the passwords. Lockwise in current Firefox releases for desktop store the logins in logins.json and key4.db (encryption key) in the Firefox profile folder and do not need internet access.

Thx 4 answer but:

1) Now I use old FF (52.9.0-esr) & install latest (78.7.x-esr). When i try manual add password from (clear FF-78) - i don see it. Only recomendation for use Sync etc. Only after restart FF-78 I see my manual inputed password in the "stored". WTF?

2) How i can migrate my local password DB from FF-52 (key3.db & login.json) to the new FF-78?

Thx 4 answer. More details:

1) Now i use old FF 52.9.0-esr. 2) I install FF 78.7.x-esr (latest) on another box. Im try manual add password. & i see only recomendation for sync etc. Only after restart FF78 i see my manualy added password. WTF? 3) How i can migrate my password DB (key3.db & logins.json) from FF52-esr to 78-esr?

Simple now i don't see how i must migrate passwords even manually....

1) FF78-esr latest dont store passwords after manual input (after restart only) 2) How i can migrate passwords DB from FF52-esr (key3.db & logins.json) to the 78-esr? 3) Why my posts permanently removed with errors from this sute?

How i Must migrate passwords DB when after each manually input password i MUST reastart FF-latest-esr?

Any tool? key3->key4 mb?

Support for key3.db ended with Firefox 73 and newer, so you need to install (or update to) either Firefox 68.9.0 ESR or install Firefox 72 to migrate the password files (key3.db to key4.db).

1) I can read changelogs

2) Im ask about resolve problem.

I try upgrade my FF52-esr, but have permanent error "could not install patch", when it upgrading from Help/About menu to the 69 (as i remember). Next - I Install new version FF-esr. And now have problrem with migrate passwords database from old-FF to the new.

Any recomendations?

And i try run FF-78 with FF-52 profile for convert key3 to the key4. This now dont work! Perfect!

You can't change key3.db to key4.db unless you run a Firefox version that supports both (58-72).

You can force Firefox 52 to switch to key4.db (SQL) by starting Firefox via a CMD (bat) file and include this line (SQL key4.db is supported in NSS 3.12 and later (2011)).

• set NSS_DEFAULT_DB_TYPE=sql

Thx 4 support. Minwhile:

What i must do 4 migrate my password DB from 52-esr to the 78-esr.

Now i dont have clear answer.

All above is crap only (sorry for my english)

PS And 68-esr with 52-profile dont convert key3 2 4.

set ? I must set env variable or type "set" word in the command line, when start FF?

My english is realy very bad.

About above:

Manual password add to the LockWise dont work (offline) if pw db is EMPTY. Added password showed after browser restart only. Seems as bug. If pw db not empty FF restart NN (fast test FF-78-latest-esr).

You need to place key3.db and logins.json in a 68 profile and delete an exiting key4.db. If you start Firefox 68 with this profile then you should get a key4.db file apart from the key3.db file and see the logins in the Password Manager if there aren't any problems.

You can possibly set signon.debug = true on the about:config page to log possible errors in the Browser Console.
