This document describes the online tracking practices that Mozilla believes, as a matter of policy, should be blocked by default by web browsers. These practices are potentially harmful to users and cannot be meaningfully understood or controlled by users. We intend to implement technical protections in Firefox to block all tracking practices included in this policy. If we discover additional trac

Fission is Mozilla's implementation of Site Isolation in Firefox. Site Isolation is a security feature that offers additional protection in case of large classes of security bugs. Site Isolation safely sandboxes web pages and web frames, isolating them from each other, further strengthening Firefox security. Why? Web security is designed in such a way that websites or webframes cannot access each

Overview The ability for extensions to interact directly with the filesystem has been one of the more controversial topics with WebExtensions. In the past this ability has been available to legacy extensions through APIs like OS.File and OS.File.DirectoryIterator and this has allowed those extensions to read and write from the filesystem with no limits. Firefox is adopting a sandboxed, multi-proce

Quantum is not a new web browser. Quantum is Mozilla's project to build the next-generation web engine for Firefox users, building on the Gecko engine as a solid foundation. Quantum will leverage the fearless concurrency of Rust and high-performance components of Servo to bring more parallelization and GPU offloading to Firefox. As the project evolves we'll be adopting more of Servo's components,

Overview “Context Graph” is a recommender system for the Web. The goal for Context Graph features is to help people find new stuff based on their current context. For example, lots of pages link to a single YouTube video, but there’s no way to get at all those pages from the YouTube video itself. If we can understand this network of links, we can use it to build a better recommendation system. Act

Complete themes are less security-sensitive than other add-ons, but they still need to be implemented with great care so they don't break the way Firefox looks. There's also the special case of multi-package installers, which are generally used to bundle a theme and a configuration extension. In this case both an extension review and a theme review are necessary. Basic testing Testing should be do
