All saved passwords have been deleted after a computer crash

I had a computer crash - it happened when I was in the process of closing one Firefox window.

After a reload, I find that all saved passwords after 2018 have been deleted. Luckily I am one of these persons that ignores advice to regularly change a password and have managed to restore most of these from memory. However, that still leaves a gmail account and reddit that I cannot log into, nor have the passwords written down.

Nothing else has been affected. Bookmarks, recent history are all there. I was even able to do a Session Restore on the pages I had open. All that is missing is about four years of saved passwords. Even the predictive text that pops the user name into the prompt for a login has gone.

Is there any way that all the passwords that should be there can be restored? Are they sitting somewhere on the computer? I don't mind manually restoring them if need be but I would like to get into these accounts.

There is a logins-backup.json file. With Firefox closed try renaming the logins.json file to, say, renlogins.json then rename the backup file to logins.json.
