Confirmed this in Firefox 19.0.2 in Kubuntu 12.04. This behavior is present both with "Never remember history" set in preferences and if Private Browsing is entered while "Remember history" is set in preferences. I also checked this on my Windows 7 install (also running Firefox 19.0.2), and this does not appear to be occurring over there.
