some logins magically disappeared
They are gone from the logins.json file that still has many others.
The saved login data (username, password) for several pages (that all sit on one and the same domain in different folders -- no idea if that matters) have suddenly disappeared. I did no Firefox update. I use no sync. There is no logins.json.corrupt file. And the logins.json file looks totally clean in a text editor. The JSON objects for those pages' URLs are simply no longer resident among the many others into whose online sites/pages I can still log in picking the saved login data. (I don't know if any other saved logins have disappeared. There are too many to mentally keep track of.)
The only thing that may be special: I added a new login for a new page on that domain, and later on the same day all of them were gone when I tried to log into one of them again.
Does anyone know how and why this can happen? Why would Firefox (version 64.0) drop certain page logins while keeping others -- and when not manually asked by me to delete any? Does it do this when there are more than 4 or 5 per a single domain? And is there any backup file somewhere when it does that? Some totally weird Firefox bug behind this or a powerful hacker attack? I am quite nonplussed. Can someone enlighten me?

Did you check the owner and (write) permissions for all the files and folders in the profile folder ?
You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
- Help -> Troubleshooting Information -> Profile Folder/Directory:
Windows: Open Folder; Linux: Open Directory; Mac: Show in Finder - https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data

(thanks for making a suggestion... my reply:)
What would that achieve?
The logins.json file can be accessed by FF after all. Other logins are still in there and working after all. The logins.json file simply no longer contained the login infos for certain pages without me having deleted them, but still contains plenty of others.
P.S.: Also, I was able to re-add some lost login data by logging in manually. So, the file access seems never to have changed. (if there are still some files helpful to check for access, let me know... I suspect the cause of the loss is something else, though)
