I should add, after recopying those two files the results did not change.

If you copy the signons.sqlite and key3.db files to the current Firefox profile folder while is closed then you should see the names and passwords in the Password Manager. That has always worked for me.

If Firefox also doesn't prompt to store a new password and you aren't in Private Browsing mode then it is likely that there is a problem with the key3.db file or the signons.sqlite file.
You can check the signons.sqlite file with the SQLite Manager extension (you will see the names and passwords encrypted).

Using the SQLite Manager to look at singons.sqlite I see a Master Table called moz_logins that shows me all the passwords I saved on my former computer. There are also 4 websites listed in the moz.disabledHosts table and 6 listings in the sqlite.stat1 table. That last table doesn't seem to be web sites though:

INSERT INTO "someTable" VALUES ("moz_disabledHosts","sqlite_autoindex_moz_disabledHosts_1","4 1");
INSERT INTO "someTable" VALUES ("moz_logins","moz_logins_encType_index","204 204");
INSERT INTO "someTable" VALUES ("moz_logins","moz_logins_guid_index","204 1");
INSERT INTO "someTable" VALUES ("moz_logins","moz_logins_hostname_httpRealm_index","204 2 2");
INSERT INTO "someTable" VALUES ("moz_logins","moz_logins_hostname_formSubmitURL_index","204 2 2");
INSERT INTO "someTable" VALUES ("moz_logins","moz_logins_hostname_index","204 2");

The passwords are still not showing up. For example, when I look at the details for my webmail page Have I saved my passwords for this website? The answer is Unknown and when I click View saved Passwords the list is empty.

Any other suggestions?

The saved names and password are in the moz_logins table (Browse and Search). If nothing shows there then there aren't any password saved or the file is corrupted.

If the key3.db file is corrupted or isn't the version that has the correct encryption key then the Password Manager won't be able to decrypt the names and passwords.

There is some code that you can run in the Browser Console (Firefox/Tools > Web Developer) in this mozillaZine knowledge base article to show the decrypted passwords in a Firefox tab. http://kb.mozillazine.org/Password_Manager

I am not a programmer, but read everything I can find on this problem. Nothing seems to address the issue I have. As I mentioned in the above update, I do see my list of encrypted passwords in the moz_logins table.

That seems to leave the key3.db file as the culprit, but I don't see how since I copied the file from my former computer and it all ran fine.

All I know is that no saved passwords show up when I look at the list of saved passwords under Options Security. And, I don't get a prompt to save a password when I do enter it on to a web page.

Any more ideas for me to try?

Is there some way to restart this request for a solution? I have not seen a response since 5/21.

Yes for sure....!!!

are you ever using these steps (mentioned above): There is some code that you can run in the Browser Console (Firefox/Tools > Web Developer) in this mozillaZine knowledge base article to show the decrypted passwords in a Firefox tab.

I saw in the similar issue link the suggestion to reset Firefox. I tried that and all the old passwords seem to be remembered now and I get the prompt to save a password when I sign up for a new site. So, that would be my advice for others who have issues with migrating to a new computer. The reset saves your old profile, so if it doesn't fix your problem you are no worse off. On the other hand it can save the time of chasing a lot of dead ends. As far as I can tell I did not lose any important history in the process, but is there anything I should be checking for? Thanks
