Mozilla: Lobbying and Site Isolation in Firefox

  • Mozilla publishes position paper on EU Digital Services Act

    In December 2020 the European Commission published the draft EU Digital Services Act. The law seeks to establish a new paradigm for tech sector regulation, and we see it as a crucial opportunity to address many of the challenges holding back the internet from what it should be. As EU lawmakers start to consider amendments and improvements to the draft law, today we’re publishing our substantive perspectives and recommendations to guide those deliberations.

    We are encouraged that the draft DSA includes many of the policy recommendations that Mozilla and our allies had advocated for in recent years. For that we commend the European Commission. However, many elements of the DSA are novel and complex, and so there is a need for elaboration and clarification in the legislative mark-up phase. We believe that with targeted amendments the DSA has the potential to serve as the effective, balanced, and future-proof legal framework.

  • Introducing Site Isolation in Firefox

    When two major vulnerabilities known as Meltdown and Spectre were disclosed by security researchers in early 2018, Firefox promptly added security mitigations to keep you safe. Going forward, however, it was clear that with the evolving techniques of malicious actors on the web, we needed to redesign Firefox to mitigate future variations of such vulnerabilities and to keep you safe when browsing the web!

    We are excited to announce that Firefox’ new Site Isolation architecture is coming together. This fundamental redesign of Firefox’ Security architecture extends current security mechanisms by creating operating system process-level boundaries for all sites loaded in Firefox for Desktop. Isolating each site into a separate operating system process makes it even harder for malicious sites to read another site’s secret or private data.

  • Introducing Site Isolation in Firefox (Mozilla security blog)

    The Mozilla Security Blog announces that there is a new site-isolation mechanism available for testing in the Firefox browser. It's a defense against Meltdown and Spectre exploits.

  • Hacks.Mozilla.Org: Introducing Firefox’s new Site Isolation Security Architecture

    Like any web browser, Firefox loads code from untrusted and potentially hostile websites and runs it on your computer. To protect you against new types of attacks from malicious sites and to meet the security principles of Mozilla, we set out to redesign Firefox on desktop.

    Site Isolation builds upon a new security architecture that extends current protection mechanisms by separating (web) content and loading each site in its own operating system process.

    This new security architecture allows Firefox to completely separate code originating from different sites and, in turn, defend against malicious sites trying to access sensitive information from other sites you are visiting.

    In more detail, whenever you open a website and enter a password, a credit card number, or any other sensitive information, you want to be sure that this information is kept secure and inaccessible to malicious actors.

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.
