Required reading
- Create a backup profile.
- Download the user.js file here (Right click >
Save Link As…).
- Review both Common Overrides and Optional Hardening to make any necessary changes.
- Open Firefox. In the URL bar, type
about:profiles and press Enter.
- For the profile you want to use, click Open Folder in the Root Directory section.
- Move the
user.js file into the folder.
After restarting Firefox:
- Get an ad blocker like uBlock Origin with our recommended filters.
- Enable DNS-level protection with your chosen provider to further protect against security threats, ads, and trackers.
Simple goals
- Minimalism: get what isn't needed out of the way
- Efficiency: unleash Firefox's ability to be fast and performant
- Privacy: protect your data without causing site breakage
Simple configs
Securefox, Peskyfox, and Smoothfox are guides to settings within Firefox. The user.js — a configuration file that controls Firefox settings — is curated from these guides.
