Firefox

Protection

Your online life belongs to you

Protection shouldn’t be a premium feature. With Firefox, it’s built in. We block trackers automatically, protect your privacy by default, and give you clear visibility into what’s happening behind the scenes.

Total cookie protection

Cookies are one of the web’s favorite tracking tools, following you from site to site and quietly building a profile of your activity. Total Cookie Protection keeps each site’s cookies separate, so companies can’t connect the dots across your browsing.

Enhanced Tracking Protection

Firefox blocks thousands of known trackers before they can follow you around the web. No setup required. Just open Firefox and browse with protection already in place. You can also see what’s being blocked by clicking the shield icon in your address bar.
