Frequently Asked Questions

Most cookies are harmless — they just remember your login or preferences. Third-party tracking cookies are a privacy concern as they track your activity across multiple websites for advertising. Firefox's Enhanced Tracking Protection blocks these by default while allowing the cookies needed for sites to function. This is a good balance for most users.
