Interaction data includes metrics such as the number of open tabs and windows, the number of webpages visited, the number and type of installed Firefox Add-ons, session length, and interactions with features offered by Mozilla or third parties. These features may include Firefox search features and search partner referrals. Technical data provides information...

This script disables Firefox's telemetry to prevent the collection and transmission of browser performance and usage data to Mozilla. Disabling telemetry prevents both the storage and transmission of this data, ensuring users' browsing habits remain private.

This script is designed to disable the "toolkit.telemetry.unified" preference. If this preference is enabled, it results in two effects: 1. Firstly, telemetry will always be enabled and recording base data. 2. Secondly, additional main pings will be sent. This preference is enabled by default. The "toolkit.telemetry.unified" preference signifies whether the Telemetry system is operating in Unified mode or not. However, it's worth noting that this feature is planned to be phased out and is consid...

This script disables the "update" ping sent from Firefox Desktop. This ping is sent when a browser update is ready to be applied and also after the update has been successfully applied. This script sets the "toolkit.telemetry.updatePing.enabled" preference to disabled, which turns off the "update" ping associated with browser updates.

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...

This script sets "toolkit.telemetry.server" to be empty. This preference defines the server to which telemetry pings are sent.

Websites can obtain your local IP address through WebRTC's peer-to-peer protocol, facilitated by JavaScript. WebRTC (Web Real-Time Communication) is a free and open-source project offering real-time communication (RTC) via application programming interfaces (APIs) to web browsers and mobile applications. It enables audio and video communication to work inside web pages by facilitating direct peer-to-peer communication, and thereby eliminating the need for plugin installations or native app downl...

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...

Fingerprinting Protection is a heavily developed experimental feature in Firefox. As part of a project to integrate features from the Tor Browser, Mozilla launched an anti-fingerprinting project in Firefox. This script enables the "privacy.resistFingerprinting" preference, activating anti-fingerprinting. As an experimental feature, it might cause some website breakages, such as impacting web speech functionality and favicons.

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,...

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", is a feature designed to enhance user privacy in Firefox. It works by allocating different, isolated storage spaces for every websit...
