After a bit more looking into it, it seems I lost saved logins specifically from accounts.google.com/ which is what I need to access

Your profile folder should contain a logins-backup.json file. With Firefox closed, rename logins.json as something else then rename the backup file to logins.json and restart Firefox.

logins-backup.json is a plain text file, so you can open this file in a text editor to see whether it contains any logins for "host accounts.google.com".

Note that you should backup your logins or possibly sync them to another device, especially if you use generated random passwords.

You can check if Windows has saved copies of logins.json and key4.db in the Firefox profile folder as part of a system restore point (do not use System Restore as that can cause more problems, but copy the files to a folder).

You can look a utility to browse System Restore points.
