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?

I came here to ask the million dollar question, they answered it on their GitHub.

How we are differnt from Librewolf? Umbra uses the built in firefox password manager instead of recommending extensions. Netflix works, and we do not enable RFP ( resist fingerprinting ) by default as it breaks many web pages. We also have an Umbra Control Center ( about:umbra or bottom left in setting menu) that allows you to set many privacy settings and set profiles for individual web sites. ( may be more differences just the top of my head)

Nice. Now - how does it differ from IronFox?

[–] jerrimu@lemmy.world 1 points 15 hours ago

I'm not super familiar with ironfox. Currently we're only available on Linux/windows. We don't use profiles at all.

Cool project. Will it support existing extension?

[–] jerrimu@lemmy.world 11 points 1 day ago (1 children)

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

Will it support sync between devices as well?

[–] anthropozaen@feddit.org 4 points 1 day ago* (last edited 1 day ago) (1 children)

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

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