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

Yeah it supports all firefox extensions. We kept the parts that don't spy on you.

Will it support sync between devices as well?

I don't like browsers phoning home, even when it's convenient. You can import history/password from another browser.

Its encrypted tho as far as i know (Unless just privacy is your concern). But Yea to each their own

If you want hardened Firefox with sync you could use Librewolf.
