Key qualities
Overview
Firefox is a privacy-focused web browser developed by Mozilla, a non-profit organization that puts your privacy first. Unlike browsers made by big tech companies, Firefox doesn't have a financial incentive to collect your data. Firefox blocks known trackers automatically through Enhanced Tracking Protection, which stops companies from following you across different websites. The browser uses Total Cookie Protection, which keeps cookies isolated to the website that created them, preventing cross-site tracking. Firefox also includes anti-fingerprinting protection that makes it harder for websites to identify you based on your browser's unique characteristics. Firefox is based on its own Gecko engine, not Google's Chromium, which means you're not dependent on Google's browser technology. The browser is open source, so anyone can verify its privacy claims. Firefox lets you control what telemetry data is shared, and you can disable it entirely if you want. Firefox Sync lets you synchronize your bookmarks, passwords, and settings across devices securely. The browser is free, works on all major platforms, and supports extensions to add even more privacy features.
