Free Downlaod Firefox Update version

Mozilla Firefox

Mozilla Firefox (known simply as Firefox) is a free and open-source web browser developed for Windows, OS X, and Linux, with a mobile version for Android, by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. Firefox uses the Gecko layout engine to render web pages, which implements current and anticipated web standards.

As of February 2015, Firefox has between 12% and 20% of worldwide usage as a "desktop" browser, making it, per different sources, the third most popular web browser. Still, the browser is most popular in several countries, as a desktop browser (or even across all platforms) including Indonesia, Germany, and Iran, at 50%,44% and 37%, of the market share, respectively.

Standards:

Firefox 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. Firefox also implements standards proposals created by the WHATWG such as client-side storage, and canvas element.

Firefox has passed the Acid2 standards-compliance test since Update version. 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. Because the SVG font tests were removed from the Acid3 test in September 2011, Firefox 4 and greater scored 100/100.

Firefox also implements a proprietary protocol from Google called "Safe browsing", used to exchange data related with phishing and malware protection.
