how can I autocomplete only username when firefox quits and re-open? If I log in to facebook or gmail and when I close firefox and return to the websites, it autocomplete username but when I quit firefox and return, it didn't autocomplete. I have my history as custom, no private browsing, 4 column down checked and "When I quit Firefox, it should automatically clear all: Browsing & Downloading History, Active Logins, Forms & Search History, Cookies and Cache. The data is all unchecked, only history is all checked. I am on a Mac
