Waterfox is a customisable browser based on Mozilla Firefox. This repository contains Mozilla platform code, Waterfox product code, branding, features, packaging, and release files.
Building
Waterfox uses the Mozilla build system. The usual ./mach entry points apply:
./mach bootstrap
./mach build
./mach package
./mach test --auto
Build, packaging, and release notes for Waterfox live in waterfox/docs/.
Contributing
Most Firefox development documentation still applies to this tree. Start with the Waterfox notes in waterfox/docs/, then use the Firefox Source Docs for the shared Mozilla build system, testing tools, and platform code.
