Browser controls to review
Firefox includes Enhanced Tracking Protection, which Mozilla documents as blocking categories of known trackers and harmful scripts. The default and stricter modes differ; a stricter setting can affect site behavior. Firefox also provides a Protections Dashboard and controls for exceptions. Check Mozilla’s current support article for the version you use.
Keep the browser lean and current
Install updates, review site permissions, and remove extensions you no longer need. An extension can access browsing information according to its permissions, so check the publisher and requested access before installing. A private window is useful for limiting local history after a session, but it does not hide you from websites, networks or accounts you sign into.
Limits
Tracking protection blocks known categories; it does not stop every tracker, fingerprinting technique, or account-based measurement. Browser settings cannot undo information you already submitted. If a site breaks under stricter protection, test a narrow exception rather than disabling protections for every site.
This profile is based on Mozilla documentation and is not a comparative performance or security test. Confirm features and availability on Mozilla’s current site before changing browsers.

Official websiteFrequently asked questions
Does Firefox tracking protection block every tracker?
No. It blocks listed categories and has configurable modes, but no browser feature blocks every form of measurement or identification.
Will stricter protection break websites?
It can affect some site features. If necessary, use a narrow site-specific exception and review it later.
