Yes, I used my favorite search engine for this a thousand times... "places.history.enabled" doesn't seem to do it, I gave "browser.history.maxStateObjectSize" = 1 a try to no avail, "browser.urlbar.autocomplete.enabled" doesn't do what the name promises... So, how do I avoid the history of visited URLs to be stored when using Firefox on Android? (I'm aware that deleting on exit might do the trick, but who explicitly exits their browser on mobile?!?) Has this feature been intentionally removed, as I see old screenshots with an explicit option?
