This is the universal build of Firefox Beta for Testers 143.0b9. It contains native libraries for every CPU architecture (arm64-v8a, armeabi-v7a, x86, x86_64), so it installs on any Android device. The trade-off is size — it's larger than per-architecture variants. Pick this one if you're unsure which CPU your phone has, or if you plan to share the APK with multiple devices.

App Description

Firefox Browser for Android is automatically private and incredibly fast. Thousands of online trackers are following you every day, collecting information about where you go online and slowing down your speed. Firefox blocks over 2000 of these trackers by default and there are ad blocker add-ons available if you want to customize your browser even more. With Firefox, you’ll get the security you deserve and the speed you need in a private, mobile browser.

FAST. PRIVATE. SAFE.

Firefox is faster than ever and gives you a powerful web browser that protects your privacy. Keep what’s personal private with Enhanced Tracking Protection, which automatically blocks over 2000 online trackers from invading your privacy. With Firefox, you don’t have to dig in your privacy settings, everything is set up automatically, but if you like to be in control, you can choose from the many ad blocker add-ons available for the browser. We designed Firefox with smart browsing features that let you take your privacy, passwords, and bookmarks with you safely wherever you go.

ENHANCED TRACKING PROTECTION AND PRIVACY CONTROL

Firefox gives you greater privacy protection while you’re on the web. Block third-party cookies and unwanted ads that follow you around the web with Enhanced Tracking Protection. Search in Private Browsing mode and you won’t be traced or tracked — your private browsing history is automatically erased when you're done.

BILLIONAIRE FREE FOR 20+ YEARS

The Firefox browser was created in 2004 by Mozilla as a faster, more private browser with more customizable features than web browsers like Internet Explorer. Today, we are still not-for-profit, still not owned by any billionaires and still working to make the internet — and the time you spend on it — better. To learn more about Mozilla, please go to

Frequently Asked Questions about Firefox Beta for Testers APK

This is the universal variant — a single APK that contains native libraries for every CPU architecture. It installs on any Android device but is larger than per-architecture variants.

Yes — the APK's signature has been cryptographically verified against the publisher's signing key. The SHA-256 hash is shown in the File Information panel so you can independently confirm the file matches the original release.

Android 21 (API level 36) or newer. Older devices will refuse the install.

Install a free app like 'CPU-Z' or 'Droid Hardware Info' from the Play Store and look at the ABI / Instruction Set row. Most phones made after 2017 are arm64-v8a; if in doubt, download the universal variant.

All variants are functionally identical — same features, same version. They differ only in which CPU architectures the native code is compiled for, and (sometimes) which screen densities the included graphics target. Pick the one that matches your device for the smallest install size, or pick 'Universal' if you're unsure.
