We built Umbra by forking, updating, and improving the ghostery browser build script, fern.js
Umbra removes all telemetry and outgoing requests except for codec requests ( netfix works!) All non-browsing features like AI, pocket, and profiles are also removed,
The idea behind umbra is usable privacy. By default RFP is off because it breaks websites.
You can build Umbra yourself but using the build script at https://github.com/openconstruct/user-agent-desktop
Or downod binaries for Linux/WIn at https://github.com/openconstruct/umbra/releases
Umbra doesn’t add any security flaws to firefox. Every security fix applied to firefox esr is also applied to Umbra.
That makes you different eh? Love that. Means I could actually use it :D
