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've used WaterFox since inception. I used to use Firefox, but after that turned into a data collection browser, I opted to switch to this one. The user interface is pleasing & the controls are also well thought out. Some of the Firefox features are included, such as tab syncing & bookmarks. All in all, a nice little browser that doesn't use a lot of resources and is privacy focused

Fantastic app with rapid support, absolutely worth using as your primary mobile browser. I seldom experience bugs, and even when they do happen the developers fix them very quickly. Not to mention, being built on Firefox, it has access to uBlock Origin (among many other very useful extensions) and therefore ZERO ADS, unlike almost every other mobile browser.

It has been great, but now every time I open, I get a half screen warning, Waterfox had to restart" Because I don't want to automatically send crash reports it takes several taps of the screen and back button to get the warning to go away. If I clear all the data and set it up again how I like, it works ok for a day, then back to the warning screen.
