In their own words
IronFox
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.
Mozilla Firefox
Mozilla Firefox is a free, open-source web browser that uses the Gecko engine. It is available on Windows, macOS, Linux, iOS, Android, and as a browser extension, and its download page lists availability in more than 90 languages. Standard tracking protection and built-in ad blocking are included. Total Cookie Protection isolates cookies so they cannot follow users between websites, while Tab Groups organize open tabs by project, mood, or task. A Mozilla account can sync bookmarks, passwords, and open tabs across devices. Firefox also offers access to multiple AI chatbots in one place, letting users choose whether to use them. Thousands of free extensions are available through addons.mozilla.org. Mozilla’s privacy notice says browsing history, form data, temporary files, and cookies are processed on the device unless stated otherwise. Automated translation and PDF alt-text suggestions use downloaded language models locally; Firefox says those features do not send page content, PDFs, images, or tab URLs to Mozilla. Firefox is listed at free.
