Waterfox: Private Web Browser

BrowserWorks

About this app

🔒 True Privacy by Design
Waterfox Android is completely rebuilt from the ground up with privacy as the foundation. Zero telemetry, no data collection, no sponsored content, and no tracking of any kind. We've created dummy versions of tracking services to maintain compatibility while protecting your privacy.

⚡ Maximum Performance
Unlike other browsers using pre-built components, we compile everything from scratch - Android Components, Gecko, and SpiderMonkey - with advanced compiler optimizations (-O3) for faster browsing and better battery life.

🧩 Full Add-on Freedom
• Browse and install from the entire Mozilla Add-ons store
• Direct installation from addons.mozilla.org
• Custom AMO collections support
• Install extensions from .xpi files
• No restrictions, no redirects

🛡️ Enhanced Security Features
• Site Isolation (Fission) enabled
• Enhanced DNS over HTTPS with Ultra Protection mode using Oblivious HTTP
• ESR (Extended Support Release) base for rock-solid stability
• about:config access for power users

🎛️ Complete Customization
• Privacy-first search engines (DuckDuckGo, Startpage, Mojeek, Qwant)
• Customizable menu designs (classic and modern)
• JPEG-XL image support
• No review prompts or forced feedback

Why Waterfox Android?
We've solved the constant breakage problem that plagued previous versions by moving to ESR and compiling everything ourselves. This means stable, fast, private browsing without compromise.

Perfect for users who want Firefox-level functionality without the privacy concerns, tracking, or performance limitations of mainstream browsers.

Ratings and reviews

I love this browser, but can we please have the option to disable the new menu back in the customization menu again? The update turned the new menu back on and I had to go back into Secret Settings to change it again. I've been using Waterfox on Android since the first run, before you brought it back on Android more recently. Thank you for everything you do.

This browser is my way of using Firefox while hating Mozilla's practices. This is a great browser, mostly thanks to Firefox's mobile app, but all the improvements and security that this app brings gives me peace of mind, and I like their stances on AI. I have been experiencing a few issues with the "Ultra Protection" thing with your partner Fastly. It returns "address not found" and I have to turn it off to use the browser. It would be nice to have this feature work again.

Good browser. However, recently it's been giving me an "Address not found" error, even when I'm not trying to get to a particular website. It does say to check your internet however any other browser I use when I have this problem, doesn't have this problem. But it does make the app completely unusable for the time it's doing this weird bug.
