Profile data can be removed or not recorded in several ways; * 1) Running Firefox in Private Mode (nothing is recorded) * 2) Privacy settings; (In the address bar,<br>type '''about:preferences#privacy'''<enter>) * 3) Many disk cleaners and anti-virus type programs can remove data from browsers. Open their settings and have them leave the browsers alone. * 4) Mal-ware. You may be in Private Browsing mode or told Firefox not to remember. Type '''about:preferences#privacy'''<enter> in the address bar. The button next to '''History, ''' select '''Use Custom Settings. ''' Turn off '''Always Use Private Browsing Mode''' Turn on '''Remember My Browsing And Download History''' At the bottom of the page, turn on '''Clear History When Firefox Closes. ''' At the far right, press the '''Settings''' button. Turn on ONLY '''Cache''' and '''Form And Search History''' leaving the others off.
