What it is

IronFox is a free, open-source web browser for Android, with privacy controls that clear browsing history, cache, download history and open tabs when the app closes. It blocks ads and trackers, enables DNS over HTTPS with Quad9 by default, and turns on HTTPS-Only Mode, proxied Google Safe Browsing and basic per-site process isolation. The project says it does not collect, store or sell user data. Based on the latest Firefox release, IronFox removes tracking and proprietary libraries, replaces Google Mobile Services with open alternatives including microG, and adds UnifiedPush support. It also supports end-to-end encrypted Firefox Sync. Installation requires Android 5 or newer, supported ARM or x86_64 architecture, and 512 MB of free disk space. IronFox warns that it cannot defeat sophisticated fingerprinting and recommends Tor Browser for some threat models. It also notes Firefox-based browsers have security deficiencies compared with Chromium, especially on Android, and that disabled Encrypted Media Extensions can prevent some DRM-protected streaming playback.
