I had this problem 2 years ago and somebody helped me fix it as follows:
(1) In a new tab, type or paste about:config in the address bar and press Enter/Return.
(2) In the search box above the list, type or paste URLB and pause while the list is filtered
(3) Double-click the browser.urlbar.autocomplete.enabled preference to switch the value from true to false
HOWEVER --- I don't seem to have browser.urlbar.autocomplete.enabled in my new version 74.0.
What happened to it? Does it have a new name now?
Note that I tried in Options / Preferences / Search
I unchecked "Show search suggestions in location bar results
In Options / Preferences / Privacy
I uncheck each of the boxes in the Location Bar section (History, Bookmarks, Open tabs).
