I upgraded my OS from Mountain Lion (10.8) to El Capitan (10.11), then upgraded Firefox. It upgraded to version 57.0.4, then required a second upgrade to 73.0.1. Now I can't see my saved logins.

I do not have Avast or AVG. I see only one profile. I have key3.db and key4.db and logins.json; no logins.json.corrupt.

Tried renaming key4.db to key4.db.save. Firefox created a new key4.db. Still can't see saved logins.

I tried changing signon.management.page.enabled and signon.management.overrideURI - I still did not see any passwords.

How can I get Firefox to transfer necessary info from key3.db to key4.db?

hi, unfortunately firefox 73 isn't able to migrate password databases in the old format anymore - this is the same issue (& hopefully solution) as discussed here for example: https://support.mozilla.org/en-US/questions/1280789

If you use the Time Machine or other backup then try to restore file(s) from this backup.

You would need older (working) copies of logins.json and key4.db (or possibly key3.db). If you need to use key3.db then make sure to remove/rename key4.db.

I think my key3.db and logins.json are ok. I just need a version of FireFox that will migrate them to key4.db.
