  • Firefox 85 crumbles cache-abusing supercookies with potent partitioning powers

    The Mozilla Foundation has scorched a pair of monstrosities in the new version 85 of its Firefox browser.

    The big target is supercookies which, as explained by Mozilla privacy engineer Steven Englehardt and senior product manager for Firefox privacy and security Arthur Edelstein, are very nasty trackers indeed because they exploit best-practice browser behaviour to offer tracking that goes beyond both that allowed by “official” Cookies and privacy laws.

    “Like all web browsers, Firefox shares some internal resources between websites to reduce overhead,” the pair explain, before offering up the Firefox cache as an example of this approach at work. “If the same image is embedded on multiple websites, Firefox will load the image from the network during a visit to the first website and on subsequent websites would traditionally load the image from the browser’s local image cache (rather than reloading from the network).”


  • The Talospace Project: Firefox 85 on POWER

    Firefox 85 declares war on supercookies, enables link preloading and adds improved developer tools (just in time, since Google's playing games with Chromium users again).


    At some point I'll get around to writing a upstreamable patch and then we won't have to keep carrying the diff around.


  • This Week in Glean: The Glean Dictionary

    On behalf of Mozilla’s Data group, I’m happy to announce the availability of the first milestone of the Glean Dictionary, a project to provide a comprehensive “data dictionary” of the data Mozilla collects inside its products and how it makes use of it. 


    Part of the vision of this project is to act as a showcase for Mozilla’s practices around lean data and data governance: you’ll note that every metric and ping in the Glean Dictionary has a data review associated with it — giving the general public a window into what we’re collecting and why.

  • Mozilla Privacy Blog: Five issues shaping data, tech and privacy in the African region in 2021

    The COVID 19 crisis increased our reliance on technology and accelerated tech disruption and innovation, as we innovated to fight the virus and cushion the impact. Nowhere was this felt more keenly than in the African region, where the number of people with internet access continued to increase and the corresponding risks to their privacy and data protection rose in tandem. On the eve of 2021 Data Privacy Day, we take stock of the key issues that will shape data and privacy in the Africa region in the coming year.

  • Mozilla Attack & Defense: Effectively Fuzzing the IPC Layer in Firefox

    The Inter-Process Communication (IPC) Layer within Firefox provides a cornerstone in Firefox’ multi-process Security Architecture. Thus, eliminating security vulnerabilities within the IPC Layer remains critical. Within this blogpost we survey and describe the different communication methods Firefox uses to perform inter-process communication which hopefully provide logical entry points to effectively fuzz the IPC Layer in Firefox.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
