Presentation

My Firefox configuration that allies privacy to practicality and simplicity. This user.js file is based on the work of Yokoffing on Betterfox , to which I've applied a series of tested modifications.

Features

• Increased speed for modern browsing experience, even on bloated sites;
• Better privacy than with default config: language spoofing, timezone spoofing in pb mode, stricter custom tracking protection, Mullvad DoH, disabled Google's Safe Browsing, Location services set to a more private alternative, HTTPS only, clear data on shutdown, no DRM, etc);
• Disabled completely Mozilla's Telemetry;
• Disabled useless features for a distraction-free and clean browsing experience (pocket, ai features, sponsored sites);
• Removed non-private search engines and added more private ones (DuckDuckGo Lite, SearX.be instance, MetaGer and Startpage);
• Maked uBlock Origin install itself automatically;
• Enhanced smooth scrolling (kinetic scrolling, adjusted sensitivity and speed).

WARNING: some parameters I have applied in this compilation breaks certain websites (mainly video communication and social media platforms), mainly because of network.http.referer.XOriginTrimmingPolicy being set to 2 and media.navigator.enabled being set to false as well as Enhanced Tracking Protection being set to Custom with strict settings.

Installation

For user.js

1. Backup your profile:

• Open Firefox and go to about:profiles;
• Check for your actual active profile ("Default Profile" should be "yes");
• On the line displaying "Root Directory", click "Open Directory";
• Close Firefox and copy all the directory's content;
• Go to this profile's parent directory in your file manager and create a new folder;
• Paste the contents into it;
• Rename the folder after the name of your profile (for a profile called kshj81bf.default, the backup copy might be called kshj81bf.default.bak).

2. Clone this repository in your home directory;
3. Review the file's content and make changes if needed;
4. Move user.js to your user's firefox profile directory:

• Open back Firefox and go to about:profiles;
• For the profile you want to use, on the line displaying "Root Directory", click "Open Directory";
• Paste the user.js file in the directory;

5. Restart Firefox.

For policies.json

1. Check for an existing directory at /etc/firefox/policies or create it;
2. Backup your current policies.json if it exists;
3. Move policies.json to the directory.
