Enable Firefox network partitioning

Overview

About this script

This script improves your privacy on Linux.

These changes use Linux system commands to update your settings.

Network partitioning is a method used by Firefox to enhance user privacy 1. When enabled, each website you visit has its own isolated storage location, preventing it from accessing data from another website 1. This limits the ability of websites to track users across multiple sites 1.

Network Partitioning, formerly referred to as cache partitioning 2, is a subset of state partitioning 1. While state partitioning deals with data like cookies, network partitioning deals with networking-related components, such as caches and connection pools 1. It ensures that these components are isolated to each website, further enhancing user privacy 1.

Firefox has enabled network partitioning by default since version 85 1. Once enabled, network partitioning becomes permanent, meaning websites cannot bypass or weaken its restrictions 1.

Network partitioning can be controlled with the privacy.partition.network_state preference 1.

This script uses Bash (Shell script) scripting language.

Safe for General Use

This script is recommended for all users. It helps to improve privacy without affecting stability.
