Google Chrome, or Chrome, is a web browser software that tries to compete with major players, such as Mozilla Firefox, Internet Explorer, Safari, and even the Opera web browser. It is available for the Linux, Android, iOS, Microsoft Windows, and Mac OS X operating systems. But Google Chrome is more than a web browser, as it combines sophisticated open source technology, borrowed from the Chromium application, into a minimal design, all in order to help users surf the web much faster, a lot easier, and safer than ever before.

What's New in version 39.0.2171.99

A unique functionality of the Google Chrome application is its ability to search the web directly from the address bar. Just type one or more words in the address bar and immediately get suggestions for popular web pages. The application displays thumbnails of your top websites on the new tab page, a function that is popularly called Speed Dial. This functionality is also available on other similar products, and it allows you to easily access your favorite web pages instantly, with lightning speed, from any new tab.
