Betterfox provides Firefox about:config preference tweaks and user.js settings intended to adjust privacy, security, and performance.
About Betterfox
Betterfox is an open-source collection of Firefox about:config preference tweaks distributed mainly as a user.js configuration file. It is described as an opinionated preference list aimed at making Firefox more private, secure, minimal and efficient without using third-party code. Alongside the curated user.js, the repository contains separate guides — Securefox, Peskyfox and Smoothfox — covering privacy settings, a distraction-free experience and smooth scrolling, plus files such as policies.json, install.py and Fastfox.js.
Installation is manual: the source advises creating a backup profile, downloading user.js, reviewing the Common Overrides and Optional Hardening sections, then placing the file in the profile's root directory (reached via about:profiles) and restarting Firefox. Separate folders exist for Waterfox and Zen. Several browsers incorporate Betterfox to some extent, but the project notes they often modify it in ways that reduce its effectiveness. No pricing information is provided.

Betterfox FAQ
How do I install Betterfox?
The source recommends creating a backup profile, downloading user.js, reviewing the Common Overrides and Optional Hardening sections, moving the file into the Firefox profile's root directory via about:profiles, and restarting Firefox.
Can Betterfox be used with Firefox forks?
The repository includes folders for Waterfox and Zen, and several other browsers incorporate Betterfox. The project notes that forks often modify it in ways that reduce its effectiveness, so applying the user.js file is still recommended.
Does Betterfox include an ad blocker or DNS protection?
No. The source directs users to get an ad blocker separately, such as uBlock Origin with recommended filters, and to enable DNS-level protection through a chosen provider.
