about:config tweaks to enhance Mozilla Firefox. Files are updated as needed for your user.js.
A secure, blazing fast browsing experience. Without breakage. The objective is to make the defaults sufficient enough for the average privacy-minded user, but remain trouble-free enough that my grandmother could use it. (That puts a whole new twist on being a foxy grandma!) Edit: Sorry for the dad joke 😓
- Minimalism: get what isn't needed out of the way
- Efficiency: unleash Firefox's ability to be fast and performant
- Security: sensible privacy and security without causing site breakage

💡 Fastfox, Securefox, Peskyfox, and Smoothfox are guides to relevant prefs in Firefox. The user.js is curated from the options located in these documents. Please read the guides to understand the various options hidden in Firefox.
Most repos have niche privacy and security concerns with little regard for speed, annoyances, or mainstream use. Betterfox was inspired by the law of diminishing returns and the minimum effective dose. For instance, features like WebGL and DRM are still enabled, and you won't find a setting like privacy.resistFingerprinting mentioned here^why?. And while Betterfox is designed to set-and-forget, it contains plenty of options for those who like to tinker.
If your context calls for anonymity and not just reasonable privacy, then please use Tor Browser.1 Fingerprinting is a high threat model issue that is only addressed reasonably by Tor.
