The Washington Post reports that exploit code for known critical unpatched security vulnerabilities in Internet Explorer was available for 284 days in 2006. īecause Firefox generally has fewer publicly known unpatched security vulnerabilities than Internet Explorer (see Perbandingan - web browsers), improved security is often cited as a reason to switch from Internet Explorer to Firefox. Official guidelines for handling security vulnerabilities discourage early disclosure of vulnerabilities so as not to give potential attackers an advantage in creating exploits. The Mozilla Foundation offers a "bug bounty" (up to 3000 USD cash reward and a Mozilla T-shirt) to researchers who discover severe security holes in Firefox. It also provides support for web applications to use smartcards for authentication purposes. It uses SSL/TLS to protect communications with web servers using strong cryptography when using the HTTPS protocol. Securityįirefox uses a sandbox security model, and limits scripts from accessing data from other web sites based on the same origin policy. įirefox also implements a proprietary protocol from Google called "Safe Browsing", used to exchange data related with phishing and malware protection. Because the SVG font tests were removed from the Acid3 test in September 2011, Firefox 4 and greater scored 100/100. Mozilla had originally stated that they did not intend for Firefox to pass the Acid3 test fully because they believed that the SVG fonts part of the test had become outdated and irrelevant, due to WOFF being agreed upon as a standard by all major browser makers. įirefox has passed the Acid2 standards-compliance test since version 3.0. Firefox also implements standards proposals created by the WHATWG such as client-side storage, and canvas element. The result of the Acid3 test on Firefox 17.įirefox implements many web standards, including HTML4 (partial HTML5), XML, XHTML, MathML, SVG 1.1 (partial), CSS (with extensions), ECMAScript ( JavaScript), DOM, XSLT, XPath, and APNG (Animated PNG) images with alpha transparency.
The nightly build was only available to those running the 64-bit RTM release of Windows 8. On October 4, 2012, Mozilla released a preview of the Metro interface version of Firefox, included in the Nightly 18 build, to be used in Windows 8. The Firefox project went through many versions before version 1.0 was released on November 9, 2004. Mozilla prefers that Firefox be abbreviated as Fx or fx, though it is often abbreviated as FF. After further pressure from the database server's development community, on February 9, 2004, Mozilla Firebird became Mozilla Firefox, often referred to as simply Firefox. In response, the Mozilla Foundation stated that the browser should always bear the name Mozilla Firebird to avoid confusion with the database software.
The replacement name, Firebird, provoked an intense response from the Firebird free database software project. Originally titled Phoenix, it was renamed because of trademark problems with Phoenix Technologies. The Firefox project has undergone several name changes. The browser has had particular success in Indonesia, Germany, Poland and Estonia, where it is the most popular browser with 65%, 47% 47% and 35% of the market share, respectively. According to Mozilla, Firefox counts over 450 million users around the world. Īs of October 2012, Firefox has approximately 20% to 24% of worldwide usage share of web browsers, making it the third most used web browser, according to different sources. Firefox uses the Gecko layout engine to render web pages, which implements current and anticipated web standards.
Mozilla Firefox is a free and open source web browser developed for Windows, OS X, Linux, and Android by Mozilla Foundation and its subsidiary, the Mozilla Corporation.
