Firefox review

Firefox is the strongest mainstream alternative to Chromium browsers and, as of November 2026, the only one here that bundles a free VPN into the browser itself. Mozilla says the built-in VPN hides your IP address, offers browsing locations in over 20 countries and includes 50 GB of protected browsing a month, and the site banner notes unlimited data through January 2027. You can turn it on for some sites and leave it off for others. Underneath, Enhanced Tracking Protection blocks known trackers by default, Total Cookie Protection keeps cookies in per-site jars, and anti-fingerprinting and Private Browsing add more layers. Firefox runs on Windows, macOS, Linux, Android and iOS, supports over 30,000 extensions and keeps AI features optional. Mozilla is nonprofit-backed and states it does not sell personal data. Defaults are a balance between privacy and compatibility, so people who want maximum hardening may prefer a Firefox-based fork such as LibreWolf.
