Enable Firefox state partitioning (Total Cookie Protection)

Overview​

About this category

This category contains privacy scripts for Linux.

These changes use Linux system commands to update your settings.

Web browsers, including Firefox, save various data types such as cookies, cache, and site-specific details. While this data helps in providing a faster and personalized browsing experience, it can be exploited by websites to track your activities across the internet, potentially compromising your privacy.

State partitioning, also known as "Total Cookie Protection" 1, is a feature designed to enhance user privacy in Firefox. It works by allocating different, isolated storage spaces for every website you visit 2. This means that each website has its own "compartment" where it saves its data, separate from other sites 2. This structure limits websites' capabilities to track users across various domains.

The underlying technology for state partitioning in Firefox is termed "double-keying" 1. In this method, when a website intends to store data, Firefox attaches an extra identifier tied to the site's origin, ensuring unique data storage for each site 1. For example, if two different sites incorporate content from the same third-party source, each of these sites will have its own unique version of the third-party's data (like cookies) due to state partitioning 1. This impedes the third-party's tracking ability between the sites.

This protection isn't just against known trackers 1. Firefox applies state partitioning to all third-party content on a site, ensuring a comprehensive privacy coverage, beyond just identifiable tracking sources 1 3.

A notable misuse by some trackers is the creation of "supercookies" 4. Contrary to standard cookies, which users can delete easily, supercookies are harder to eliminate and block, posing a considerable privacy challenge. Through state partitioning, Firefox renders supercookies ineffective for tracking users across sites 4. As a part of this feature, Firefox not only ensures site-specific data but also partitions multiple caches, such as HTTP cache, image cache, and favicon cache 4. This partitioning prevents any potential cache exploitation for tracking purposes 4.

In summary, enabling state partitioning in Firefox is a powerful privacy tool, helping to defend users from potential online tracking and offering a more private browsing experience.

Enable dynamic First-Party Isolation (dFPI)

Dynamic First-Party Isolation, also known as dFPI, is an advanced privacy feature in Firefox. This feature commonly referred to as: Total Cookie Protection, • dFPI (dynamic First-Party Isolation), • Dynamic storage partitioning. Essentially, dFPI is an enhanced version of a previous privacy tool known as First-Party Isolation (FPI). The primary purpose of dFPI is to improve user privacy online. It accomplishes this by preventing third-party websites from accessing or tracking a user's data acros...

Enable Firefox network partitioning

Network partitioning is a method used by Firefox to enhance user privacy. When enabled, each website you visit has its own isolated storage location, preventing it from accessing data from another website. This limits the ability of websites to track users across multiple sites. Network Partitioning, formerly referred to as cache partitioning, is a subset of state partitioning. While state partitioning deals with data like cookies, network partitioning deals with networking-related components,...

Disable outdated Firefox First-Party Isolation (FPI)

First-party isolation (FPI) helps in preventing third parties from tracking users across multiple websites. This is sometimes referred to as "double keying" (double-keying) or supercookies. This script disables FPI in favor of a newer technology called dynamic First-Party Isolation (dFPI) for the following reasons: 1. FPI and dFPI conflict with each other, and they cannot function simultaneously. Additionally, Mozilla doesn't plan to make them compatible. 2. FPI has been marked as deprecated and...
