Can I retrieve deleted passwords
I have deleted all my saved logins and passwords from Mozilla thinking they were all synchronized, and stored in the cloud. However, after reinstalling Mozilla on my PC, I logged in again and noticed that I only had the very old logins and passwords. Out of about 190 deleted logins, I only retrieved 58, most of them with old, inactive passwords. Looks like the recent logins had not been synchronized. Recently I changed most of my passwords to very strong ones, about 15 character long, and very complicated. Is there any way of getting the recent logins and passwords back? I would really appreciate any help.

If you were synced at the time, then the passwords were deleted from the sync as well.
If you can't get them back, you will need to use the 'Forget Password' link on all websites. This will send a temporary password to the e-mail listed on that site.
Look on your desktop. Do you see a folder called; Old Firefox? Look inside. Look for the folder with the latest creation date.
In the event that the passwords information is lost, you should record all information in a separate text file somewhere else on your hard drive, or written down. You can easily copy and paste if you need to do so. If you are concerned about someone else looking at that file, you can compress it using a password.
Firefox 80+ has a logins-backup.json file in the profile folder that can be used in case of issues with logins.json or to undo an accidental delete of a login, so you can check if you can find this file in the profile folder or in a backup.
