Brower closing and altering my settings

Every Sunday/early Monday the Firefox browser on my Mac shuts down and then re-opens with different settings and search engine. I have been through processes with Apple to ensure "safety" but it still does it. What is causing it and how can I stop it?

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, 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.

Sometimes when the browser thinks there is a problem with the profile, it will create a new one.


Look on your desktop. Do you see a folder called; Old Firefox? Look inside. Look for the folder with the latest creation date.
