Hi I have saved my old Firefox profile and copied it into the new one, but the old profile had key3.db file for passwords, while the new profile has key4.db file. I guess that's why I can't see my old saved passwords in my new version of Firefox which is a lot newer than the old one. What can I do to fix it?

If you have new passwords in your profile, this will not work.

In the new profile, remove the password files; key3.db [v58+] key4.db and logins.json : These are the Password files.

Now Copy those same files from the old profile. This must be done with Firefox Closed.

Yes, it works now. Thank you. I was overwitting those files before, but I think that it wasn't working because Firefox was open.

Well done. With Any program, never do anything with its files unless you close the program first. If you don't, there could be trouble.
