I accidentally erased all the data on your hard drive. I restored files key3.db and logins.json using R-Studio. I started putting these files to a new profile Firefox, but the passwords in the browser did not appear. I did not have master password. I deleted several files logins.json those in which was gibberish, leaving only such:

{"nextId":35,"logins":[{"id":1,"hostname":"https://mail.ru","httpRealm":null,"formSubmitURL":"https://auth.mail.ru","usernameField":"Login","passwordField":"Password","encryptedUsername":"MDIEEPgAAAAAAAAAAAAAAAAAAAEwFAYIKoZIhvcNAwcECHXGJtc4Go5cBAhRFysAGjEeyQ==","encryptedPassword":"MDIEEPgAAAAAAAAAAAAAAAAAAAEwFAYIKoZIhvcNAwcECD/UeoeJZiHlBAgBmrjidXQMLQ==","guid":"{04cdb69a-38d7-43b4-80d2-8132eee2510e}","encType":1,"timeCreated":1411633275783,"timeLastUsed":1422621681145,"timePasswordChanged":1411633275783,"timesUsed":106},{"id":2,"hostname":"https://mail.rambler.ru","httpRealm":null,"formSubmitURL":"https://id.rambler.ru","usernameField":"profile.login","passwordField":"profile.password","encryptedUsername":"MDoEEPgAAAAAAAAAAAAAAAAAAAEwFAYIKoZIhvcNAwcECHN/uPaDEsu0BBANJZY/mTxX/Nh8JGNMMUjx","encryptedPassword":"MDoEEPgAAAAAAAAAAAAAAAAAAAEwFAYIKoZIhvcNAwcECAamNsPLl++2BBCLwsU3GufYyZ8OJxuy8jPy","guid":"{58521b82-d770-44cf-aac7-7ec7e05d9cf1}","encType":1,"timeCreated":1412086220324,"timeLastUsed":1422618114443,"timePasswordChanged":1412086220324,"timesUsed":133},


I deleted the files key3.db those that were exact duplicates (using special software). When I tried to open the remaining files key3.db using Microsoft Access, then to open these files I needed a password, which I do not know. I can not understand which file key3.db matches to which file logins.json. How do I recover passwords or even usernames? Is it possible to recover passwords brute force? If yes, what program it is necessary to use for this purpose? Thanks in advance.

You will need a a master password. Hopefully you remember the passwords used. If so it is relatively simple to try all those passwords with the relevant file pairs installed in a Firefox profile. If available the files dates may help you pair them correctly.

I doubt brute force methods would work, but that is outside of my area of knowledge.

You obviously already understand how Firefox handles passwords and logins. For the benefit of other readers of this thread

A brute force won't work because that would still require the correct key3.db file as a brute force would only apply to the master password and would still need the proper encryption key stored in key3.db.

Did the restored key3.db files come with a time stamp? Files that span multiple clusters can easily get fragmented and in such a case it is not possible to restore them automatically. The key3.db file is 16 KB and if you were able to restore multiple copies that were identical then it is likely that this file is OK, especially if you haven't changed the Master Password recently.

A problem with the logins.json file is more likely also because you felt the need to edit the file because the restored copy looked corrupted. Maybe you need to try to restore an older copy or possibly try to recover a signon.sqlite file although that file is probably larger in size and thus will span more clusters. You need to remove the logins.json file and reset the signon.importedFromSqlite pref to make Firefox process the signons.sqlite file.
