Google Chrome:

Google Chrome is a freeware web browser[9] developed by Google. It used the WebKit layout engine until version 27 and, with the exception of its iOS releases, from version 28 and beyond uses the WebKit fork Blink.[10][11][12] It was first released as a beta version for Microsoft Windows on September 2, 2008, and as a stable public release on December 11, 2008. As of 2013, StatCounter estimates that Google Chrome has a 39% worldwide usage share of web browsers, making it the most widely used web browser in the world.[13] In September 2008, Google released the majority of Chrome's source code as an open source project called Chromium, on which Chrome releases are still based. Notable components that are not open source are the built-in PDF viewer and the built-in Flash player.
Google's Eric Schmidt opposed the development of an independent web browser for six years. He stated that "at the time, Google was a small company," and he did not want to go through "bruising browser wars." After co-founders Sergey Brin and Larry Page hired several Mozilla Firefox developers and built a demonstration of Chrome, however, Schmidt admitted that "It was so good that it essentially forced me to change my mind.

Development

Chrome was assembled from 25 different code libraries from Google and third parties such as Mozilla's Netscape Portable Runtime, Network Security Services, NPAPI, Skia Graphics Engine, SQLite, and a number of other open-source projects.[36] The V8 JavaScript virtual machine was considered a sufficiently important project to be split off (as was Adobe/Mozilla's Tamarin) and handled by a separate team in Denmark coordinated by Lars Bak at Aarhus. According to Google, existing implementations were designed "for small programs, where the performance and interactivity of the system weren't that important", but web applications such as Gmail "are using the web browser to the fullest when it comes to DOM manipulations and JavaScript", and therefore would significantly benefit from a JavaScript engine that could work faster. Chrome uses the Blink rendering engine to display web pages. Based on WebKit, Blink only uses WebKit's "WebCore" components while substituting all other components, such as its own multi-process architecture in place of WebKit's native implementation.[37] Chrome is internally tested with unit testing, "automated user interface testing of scripted user actions", fuzz testing, as well as WebKit's layout tests (99% of which Chrome is claimed to have passed), and against commonly accessed websites inside the Google index within 20–30 minutes.[20] Google created Gears for Chrome, which added features for web developers typically relating to the building of web applications, including offline support.[20] However, Google phased out Gears in favor of HTML5.[38]

Comprehensive Protection

Privacy Another hugely popular feature, Incognito mode allows you to browse privately by disabling history recording, reducing traceable breadcrumbs and removing tracking cookies on shutdown. Chrome’s settings also allow you to customize regular browsing privacy preferences. Security Chrome’s Sandboxing prevents malware automatically installing on your computer or affecting other browser tabs. Chrome also has Safe Browsing technology built in with malware and phishing protection that warns you if you encounter a website suspected of containing malicious software/activity. Regular automatic updates ensure security features are up to date and effective. Customi
