For the official LibreWolf browser

LibreWolf is great. PrivacyFox makes it even better.

PrivacyFox is a transparent configuration layer for a real, unmodified LibreWolf install. Every pref is checked against LibreWolf's own real defaults first — only genuine gaps get added, nothing gets fought or duplicated.

PrivacyFox / configuration map

Diffed, not layered

Every value has a reason.

  1. 1

    /etc/librewolf/policies/policies.json

    Accounts off; seven maintained privacy extensions installed alongside LibreWolf's own uBlock Origin.

  2. 2

    PrivacyFox.js → user.js

    89 prefs, not 207 — checked against LibreWolf's own real defaults first, only genuine gaps added.

  3. 3

    chrome/userContent.css

    A small cleanup for the one dead menu entry with no policy switch.

01 / Current support

Debian and Ubuntu-family Linux, on any desktop environment.

02 / Start with LibreWolf

Install it yourself, or let the installer add it for you. No manual profile step needed either way.

03 / No disguise

No LibreWolf binary is recompiled, repackaged, or redistributed here.

A deliberate baseline

Hardening that stays inspectable.

PrivacyFox is specific about what it changes and equally specific about what it leaves alone. The configuration is ordinary LibreWolf and Gecko machinery you can read, replace, or remove.

⌁

Policy, not paint

Firefox Accounts disabled at the policy level — the one real gap left in LibreWolf's own hardening that this project closes.

≡

A properly diffed hardening file

Arkenfox and Betterfox preferences, checked against LibreWolf's own real defaults first — 3 deliberate LibreWolf choices are respected, not overridden.

◌

A curated extension baseline

ClearURLs, LocalCDN, CanvasBlocker, Don’t Track Me Google, Port Authority, and Privacy Badger, force-installed alongside LibreWolf's own uBlock Origin.

↗

Updates stay upstream

LibreWolf keeps its own release cadence and security updates. PrivacyFox does not become a browser vendor in the middle.

Two real installation paths

Choose the path that fits how you manage your machine.

Install the downloadable Debian package and run one user command, or use the repository’s direct installer. Both layer configuration over your existing LibreWolf install.
