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


I came here to ask the million dollar question, they answered it on their GitHub.
Nice. Now - how does it differ from IronFox?
I’m not super familiar with ironfox. Currently we’re only available on Linux/windows. We don’t use profiles at all.
