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


Congratulations!
Tradeoff question—
Should I expect to find some semblance of safety in sticking with the largest open source browser project I can find, given perhaps the eyeballs etc., or would you reckon not (or even perhaps the opposite, security through obscurity & Umbra is “safer” than Firefox)?
Maybe this is so “lightly” forked it’s “just” stripping + cosmetics & the risk profile is essentially identical?
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
