Profile data can be removed or not recorded several ways;

  • 1) Running Firefox in Private Mode (nothing is recorded)
  • 2) Privacy settings; (In the address bar, 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.

Note: Some software, like Advanced SystemCare with Surfing Protection, can protect files in the Firefox profile folder against changes. If you have such software then check the settings or uninstall this software.
