I’m currently using Librewolf primarily, as it has good out of the box privacy settings. I really just added Ublock Origin on top of it. I’ve recently seen another uptick in Zen recommendations though, and I must admit that I like the UI. I’m sure it has worse defaults than Librewolf, so what are the things I should probably apply and what extensions should I download for some extra privacy?
And is the browser even any good beyond the initial impression?
Zen is basically Firefox with different UI. It is a security/privacy downgrade from Librewolf. You can configure Zen to have the same security/privacy settings by putting
about:configin the URL bar change some of the toggles.Use either the Arkenfox (also available in the interactive live viewer online) or Phoenix user.js as a template. Basically: disable WebGL, set WebRTC to disable nonproxied udp, disable JavaScript JIT, enable privacy.resistFingerprinting (optionally enable privacy.resistFingerprinting.letterboxing for screen fingerprint protection) and some other things.
Phoenix has some configs for Zen iirc which you can just patch. It is less strict than Librewolf when it comes to fingerprint protections (softening some of RFP’s protections).
If you want to test that the fingerprint protections are working, use this test site by Arkenfox called TorZillaPrint.
