What Is Konqueror the Problem Solution
http://www.linuxhowtos.org/Network/fastkonqueror.pdf What is Konqueror Konqueror is the default browser/file manager for KDE. As time of this writing this is one of only 4 browsers who correctly display the acid2 test (http://www.webstandards.org/act/acid2/) correctly. The Problem One problem of this browser is the lack of an internal dns cache, that means for every http request (each image on a web page) it sends a dns query. Depending on your internet connection and speed of your dns servers, this can slow things down. Solution pdnsd pdnsd is a tiny dns proxy. pdnsd should be available on most distributions. Just install the tool via apt-get, rpm, emerge or whatever your distribution uses. configuring you can use the default example configuration and modify the cache size and dns server ip. My config reads this: global { perm_cache=2048; # cachesize in kB. cache_dir="/var/cache/pdnsd"; run_as="pdnsd"; server_ip = 127.0.0.1; status_ctl = on; paranoid=on; min_ttl=900; # store cache at least 15 minutes. max_ttl=604800; # store cache maximum one week. timeout=10; } server { label= "myisp"; ip = 192.168.0.1; # enter IP of your dns server proxy_only=on; timeout=4; uptest=if; interface=eth0; interval=600; purge_cache=off; } modify /etc/resolv domain yourdomain server 127.0.0.1 start the dns proxy /etc/init.d/pdnsd start page 1 of 2 http://www.linuxhowtos.org/Network/fastkonqueror.pdf check if the server works by pinging a server ping www.linuxhowtos.org if everything works, add the pdnsd to the started services and you are done. -

05_096970 ch01.qxp 4/20/07 11:27 PM Page 3 1 Introducing Cascading Style Sheets Cascading style sheets is a language intended to simplify website design and development. Put simply, CSS handles the look and feel of a web page. With CSS, you can control the color of text, the style of fonts, the spacing between paragraphs, how columns are sized and laid out, what back- ground images or colors are used, as well as a variety of other visual effects. CSS was created in language that is easy to learn and understand, but it provides powerful control over the presentation of a document. Most commonly, CSS is combined with the markup languages HTML or XHTML. These markup languages contain the actual text you see in a web page — the hyperlinks, paragraphs, headings, lists, and tables — and are the glue of a web docu- ment. They contain the web page’s data, as well as the CSS document that contains information about what the web page should look like, and JavaScript, which is another language that pro- vides dynamic and interactive functionality. HTML and XHTML are very similar languages. In fact, for the majority of documents today, they are pretty much identical, although XHTML has some strict requirements about the type of syntax used. I discuss the differences between these two languages in detail in Chapter 2, and I also pro- vide a few simple examples of what each language looks like and how CSS comes together with the language to create a web page. In this chapter, however, I discuss the following: ❑ The W3C, an organization that plans and makes recommendations for how the web should functionCOPYRIGHTED and evolve MATERIAL ❑ How Internet documents work, where they come from, and how the browser displays them ❑ An abridged history of the Internet ❑ Why CSS was a desperately needed solution ❑ The advantages of using CSS 05_096970 ch01.qxp 4/20/07 11:27 PM Page 4 Part I: The Basics The next section takes a look at the independent organization that makes recommendations about how CSS, as well as a variety of other web-specific languages, should be used and implemented. -
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. -

Designing a Browser to Benefit from Multi-Core Silicon
Designing a Browser to Benefit from Multi-core Silicon Ekioh Ltd, Cambridge UK. [email protected] Abstract This paper investigates the impact of the evolution in processor technology upon HTML browser performance, highlighting some limitations in current browser design and ways in which these limitations can be overcome. It asserts that overcoming these limitations is key to offering 4K UIs on mass-market consumer products in the very near future. Introduction HTML browsers are increasingly being used for Trends of CE Processor Speeds application rendering and user interface (UI) 25 presentation.

Web Browsers
WEB BROWSERS Page 1 INTRODUCTION • A Web browser acts as an interface between the user and Web server • Software application that resides on a computer and is used to locate and display Web pages. • Web user access information from web servers, through a client program called browser. • A web browser is a software application for retrieving, presenting, and traversing information resources on the World Wide Web Page 2 FEATURES • All major web browsers allow the user to open multiple information resources at the same time, either in different browser windows or in different tabs of the same window • A refresh and stop buttons for refreshing and stopping the loading of current documents • Home button that gets you to your home page • Major browsers also include pop-up blockers to prevent unwanted windows from "popping up" without the user's consent Page 3 COMPONENTS OF WEB BROWSER 1. User Interface • this includes the address bar, back/forward button , bookmarking menu etc 1. Rendering Engine • Rendering, that is display of the requested contents on the browser screen. • By default the rendering engine can display HTML and XML documents and images Page 4 HISTROY • The history of the Web browser dates back in to the late 1980s, when a variety of technologies laid the foundation for the first Web browser, WorldWideWeb, by Tim Berners-Lee in 1991. • Microsoft responded with its browser Internet Explorer in 1995 initiating the industry's first browser war • Opera first appeared in 1996; although it have only 2% browser usage share as of April 2010, it has a substantial share of the fast-growing mobile phone Web browser market, being preinstalled on over 40 million phones.
