  • Security Analysis of Firefox Webextensions
    6.857: Computer and Network Security Due: May 16, 2018 Security Analysis of Firefox WebExtensions Srilaya Bhavaraju, Tara Smith, Benny Zhang srilayab, tsmith12, felicity Abstract With the deprecation of Legacy addons, Mozilla recently introduced the WebExtensions API for the development of Firefox browser extensions. WebExtensions was designed for cross-browser compatibility and in response to several issues in the legacy addon model. We performed a security analysis of the new WebExtensions model. The goal of this paper is to analyze how well WebExtensions responds to threats in the previous legacy model as well as identify any potential vulnerabilities in the new model. 1 Introduction Firefox release 57, otherwise known as Firefox Quantum, brings a large overhaul to the open-source web browser. Major changes with this release include the deprecation of its initial XUL/XPCOM/XBL extensions API to shift to its own WebExtensions API. This WebExtensions API is currently in use by both Google Chrome and Opera, but Firefox distinguishes itself with further restrictions and additional functionalities. Mozilla’s goals with the new extension API is to support cross-browser extension development, as well as offer greater security than the XPCOM API. Our goal in this paper is to analyze how well the WebExtensions model responds to the vulnerabilities present in legacy addons and discuss any potential vulnerabilities in the new model. We present the old security model of Firefox extensions and examine the new model by looking at the structure, permissions model, and extension review process. We then identify various threats and attacks that may occur or have occurred before moving onto recommendations.

  • Mozilla/Firefox: MDN Web Docs, Recommended Extensions and Tenfourfox FPR23 for Intel
    Published on Tux Machines (http://www.tuxmachines.org) Home > content > Mozilla/Firefox: MDN Web Docs, Recommended Extensions and TenFourFox FPR23 for Intel Mozilla/Firefox: MDN Web Docs, Recommended Extensions and TenFourFox FPR23 for Intel By Rianne Schestowitz Created 12/06/2020 - 5:32am Submitted by Rianne Schestowitz on Friday 12th of June 2020 05:32:58 AM Introducing the MDN Web Docs Front-end developer learning pathway[1] The MDN Web Docs Learning Area (LA) was first launched in 2015, with the aim of providing a useful counterpart to the regular MDN reference and guide material. MDN had traditionally been aimed at web professionals, but we were getting regular feedback that a lot of our audience found MDN too difficult to understand, and that it lacked coverage of basic topics. Fast forward 5 years, and the Learning Area material is well-received. It boasts around 3.5?4 million page views per month; a little under 10% of MDN Web Docs? monthly web traffic. At this point, the Learning Area does its job pretty well. A lot of people use it to study client- side web technologies, and its loosely-structured, unopinionated, modular nature makes it easy to pick and choose subjects at your own pace. Teachers like it because it is easy to include in their own courses. Recommended extensions ? recent additions [2] When the Recommended Extensions program debuted last year, it listed about 60 extensions. Today the program has grown to just over a hundred as we continue to evaluate new nominations and carefully grow the list. The curated collection grows slowly because one of the program?s goals is to cultivate a fairly fixed list of content so users can feel confident the Recommended extensions they install will be monitored for safety and security for the foreseeable future.

  • Mitigating Javascript's Overhead with Webassembly
    Samuli Ylenius Mitigating JavaScript’s overhead with WebAssembly Faculty of Information Technology and Communication Sciences M. Sc. thesis March 2020 ABSTRACT Samuli Ylenius: Mitigating JavaScript’s overhead with WebAssembly M. Sc. thesis Tampere University Master’s Degree Programme in Software Development March 2020 The web and web development have evolved considerably during its short history. As a result, complex applications aren’t limited to desktop applications anymore, but many of them have found themselves in the web. While JavaScript can meet the requirements of most web applications, its performance has been deemed to be inconsistent in applications that require top performance. There have been multiple attempts to bring native speed to the web, and the most recent promising one has been the open standard, WebAssembly. In this thesis, the target was to examine WebAssembly, its design, features, background, relationship with JavaScript, and evaluate the current status of Web- Assembly, and its future. Furthermore, to evaluate the overhead differences between JavaScript and WebAssembly, a Game of Life sample application was implemented in three splits, fully in JavaScript, mix of JavaScript and WebAssembly, and fully in WebAssembly. This allowed to not only compare the performance differences between JavaScript and WebAssembly but also evaluate the performance differences between different implementation splits. Based on the results, WebAssembly came ahead of JavaScript especially in terms of pure execution times, although, similar benefits were gained from asm.js, a predecessor to WebAssembly. However, WebAssembly outperformed asm.js in size and load times. In addition, there was minimal additional benefit from doing a WebAssembly-only implementation, as just porting bottleneck functions from JavaScript to WebAssembly had similar performance benefits.

The thesis is equivalent to 10 weeks of full-time studies. Contact Information: Author(s): Morgan Persson E-mail: [email protected] University advisor: Emil Folino Department of Computer Science Faculty of Computing Internet : www.bth.se Blekinge Institute of Technology Phone : +46 455 38 50 00 SE–371 79 Karlskrona, Sweden Fax : +46 455 38 50 57 Abstract Background. Websites of 2020 are often feature rich and highly interactive ap- plications. JavaScript is a popular programming language for the web, with many frameworks available. A common denominator for highly interactive web applica- tions is the need for efficient methods of manipulating the Document Object Model to enable a solid user experience. Objectives. This study compares Vanilla JavaScript and the JavaScript frameworks Angular, React and Vue.js in regards to DOM performance, DOM manipulation methodology and application size. Methods. A literature study was conducted to compare the DOM manipulation methodologies of Vanilla JavaScript and the selected frameworks. An experiment was conducted where test applications was created using Vanilla JavaScript and the selected frameworks. These applications were used as base for comparing applica- tion size and for comparison tests of DOM performance related metrics using Google Chrome and Firefox. Results. In regards to DOM manipulation methodology, there is a distinct difference between Vanilla JavaScript and the selected frameworks.

Data collections were sponsored from the SNF (100001CL_182630/1) and DFG (MA 2244/9-1) grant for the project “Reciprocal relations between populist radical-right attitudes and political information behaviour: A longitudinal study of attitude development in high- choice information environments” lead by Silke Adam (U of Bern) and Michaela Maier (U of Koblenz-Landau) and FKMB (the Friends of the Institute of Communication and Media Science at the University of Bern) grant “Algorithmic curation of (political) information and its biases” awarded to Mykola Makhortykh and Aleksandra Urman. Running Head: ALGORITHM AUDITING AT A LARGE-SCALE 2 Abstract Algorithm audits have increased in recent years due to a growing need to independently assess the performance of automatically curated services that process, filter and rank the large and dynamic amount of information available on the internet. Among several methodologies to perform such audits, virtual agents stand out because they offer the ability to perform systematic experiments, simulating human behaviour without the associated costs of recruiting participants. Motivated by the importance of research transparency and replicability of results, this paper focuses on the challenges of such an approach. It provides methodological details, recommendations, lessons learned and limitations that researchers should take into consideration when setting up experiments with virtual agents.

  • Identifying Javascript Skimmers on High-Value Websites
    Imperial College of Science, Technology and Medicine Department of Computing CO401 - Individual Project MEng Identifying JavaScript Skimmers on High-Value Websites Author: Supervisor: Thomas Bower Dr. Sergio Maffeis Second marker: Dr. Soteris Demetriou June 17, 2019 Identifying JavaScript Skimmers on High-Value Websites Thomas Bower Abstract JavaScript Skimmers are a new type of malware which operate by adding a small piece of code onto a legitimate website in order to exfiltrate private information such as credit card numbers to an attackers server, while also submitting the details to the legitimate site. They are impossible to detect just by looking at the web page since they operate entirely in the background of the normal page operation and display no obvious indicators to their presence. Skimmers entered the public eye in 2018 after a series of high-profile attacks on major retailers including British Airways, Newegg, and Ticketmaster, claiming the credit card details of hundreds of thousands of victims between them. To date, there has been little-to-no work towards preventing websites becoming infected with skimmers, and even less so for protecting consumers. In this document, we propose a novel and effective solution for protecting users from skimming attacks by blocking attempts to contact an attackers server with sensitive information, in the form of a Google Chrome web extension. Our extension takes a two-pronged approach, analysing both the dynamic behaviour of the script such as outgoing requests, as well as static analysis by way of a number of heuristic techniques on scripts loaded onto the page which may be indicative of a skimmer.

Multimedia y Desarrollo Web Antes de tratar cualquier asunto relacionado con los entornos de programación para la Web, es preciso comentar que no es necesario tener conocimientos previos del lenguaje de marcado HTML, pero deberíamos estar, al menos, familiarizado con el uso básico de computadoras, y usar la Web pasivamente (por lo menos haber utilizado un navegador o buscador web para consumir contenido de la Web) Debemos tener claro que es fundamental para un Programador Web contar con un entorno de trabajo básico y entender cómo crear, gestionar archivos y carpetas que encontramos en el sistema operativo de nuestro ordenador. Ahora bien, Internet es una red que conecta ordenadores a través de todo el planeta, para compartir contenidos alojados, a través de algunos de esos ordenadores, normalmente denominados servidores. Así, cada servidor puede contener algún tipo de recurso o de servicio. El servicio más extendido de Internet es sin duda la World Wide Web; es decir, la red de servidores de páginas web. Los servidores de la World Wide Web contienen páginas web que pueden ser consultadas por cualquier usuario para acceder a información e incluso interactuar con ellas, comportándose como verdaderas aplicaciones. Las páginas web internamente se estructuran como archivos de texto que, al ser transferidos al ordenador o al dispositivo del usuario, pueden ser interpretados con sentido por un navegador web, como Firefox, Chrome, Opera, Safari, etc. Para que los navegadores puedan entender correctamente las páginas web, éstas utilizan un conjunto de normas denominadas HTML (que viene de HyperText Markup Language), que son empleadas para definir la estructura semántica de la información contenida en una página web.

  • Download Chromium Windows Latest Version Chromium for Windows
    download chromium windows latest version Chromium for Windows. Chromium is the open-source version of the vastly popular Google Chrome. It features the development build that they use to continue to update the latest versions of the web. While it is different, it remains similar to the regular Chrome. User Interface. Chromium is quite similar to Chrome as they are based on Chromium OS. It features the all-in-one tab that has the setting and bookmarks. There is no scrolling mechanism for when you open up too many tabs, making it difficult to switch between them when you have many open. Features. The main characteristic Chromium comes with is the ability to have all your Google account information synchronised with it. The software is ideal for people who are developing websites or who want to develop extensions, as they can make the most of the dev build. It also comes with the ability to use a wide variety of extensions to make the user’s life easier. Google Translate comes pre-loaded into the browser. It is safe and has no viruses. Problems. The main issue with it is the lack of updates. You will have to ensure that your version remains up to date. Finding these upgrades can be a hassle because there are a variety of versions on the internet. While the browser is one of the fastest, it consumes a lot of RAM. This problem worsens if you keep a lot of tabs open. Alternatives. Google Chrome is the first competitor as it’s almost identical.
