Umbra Browser

Umbra is a privacy-focused web browser built for users who want maximum protection without the configuration headaches. Created by forking the now-discontinued Ghostery Browser's build system, Umbra sits on a hardened Firefox ESR foundation and strips out every ounce of telemetry and outbound calling—no phoning home, no data collection, no exceptions beyond essential codec downloads. It comes with uBlock Origin preinstalled and pre-configured, so you're protected from trackers and ads the moment you launch, not after twenty minutes of tweaking settings. What sets Umbra apart from other Firefox forks is its lineage and zero-maintenance design. While Ghostery Browser is no longer maintained, Umbra carries forward its battle-tested build architecture while eliminating the commercial baggage. There's no account required, no sync infrastructure to trust, and no "optional" features that quietly compromise your privacy. Every setting is locked down by default: no WebRTC leaks, no prefetching, no speculative connections—just a clean, fast browsing experience that respects your autonomy. Umbra is ideal for privacy refugees migrating from Ghostery Browser, anyone exhausted by Firefox's increasingly aggressive data collection, or users who want LibreWolf-level hardening without the manual setup. It runs on Windows, macOS, and Linux, with a minimal resource footprint that stays out of your way. If you believe browsers should serve users—not advertisers, data brokers, or platform owners—Umbra is built for you.
