Google Chrome is an open source web browser made by Google. Since, 2008 Google Chrome has been one of the major inventions by Google.inc . The first version was a beta for Microsoft Windows was released on September 2, 2008 in 43 languages.OS X and Linux versions were released in December 2009.
Chrome includes an Incognito mode (similar to Safari's Private Browsing and Internet Explorer 8's InPrivate) which "lets you browse the web in complete privacy because it doesn’t record any of your activity" and discards cookies. When enabled for a window "nothing that occurs in that window is ever logged on your computer.
The main User Interface includes back, forward, refresh, bookmark, go and cancel options similar to Safari browser, while the settings location looks like Internet Explorer 7/8. The minimize, maximize and close window buttons are based on Windows Vista
Chrome includes Gears which adds developer features that may or may not become web standards, typically relating to the building of web applications (including offline support).
New Tab Page
Chrome replaces the browser home page which is displayed when a new tab is created with a New Tab Page. This shows thumbnails of the eight most visited web sites along with the sites most often searched, recent bookmarks and recently closed tabs. This concept appeared first with Opera's Speed Dial.
The Omnibox is the URL box at the top of each tab, based on the one in Opera. It includes autocomplete functionality but will only autocomplete URLs that were manually entered (rather than all links), search suggestions, top pages (previously visited), popular pages (unvisited) and text search over history. Search engines can also be captured by the browser when used via the native user interface by pressing Tab.
Popup windows "are scoped to the tab they came from" and will not appear outside the tab unless the user explicitly drags them out. It is not clear whether they also run in their own process.
Chrome uses the WebKit rendering engine on advice from the Android team. The WebKit engine is simple, memory efficient, useful on embedded devices and easy to learn for new developers.
Tabs are the primary component of Chrome's user interface and as such have been moved to the top of the window rather than below the controls (similar to Opera). This subtle change is in contrast to many existing tabbed browsers which are based on windows containing tabs. Tabs (including their state) can be seamlessly transferred between window containers by dragging. Each tab has its own set of controls, including the Omnibox URL box.
Google Chrome fails the Acid 3 TestGoogle Chrome passes the Acid2 test prior to window resizing The first release of Google Chrome Beta (Build 1583) did not pass the Acid3 test; it scored 77/100 and does not render the image correctly. It passed the Acid2 test initially, but failed upon resizing. From version 4 onward, Google Chrome has passed the Acid1, 2,and 3 tests.
Webapps can be launched in their own streamlined window without the Omnibox URL box and browser toolbar. This limits the browser chrome so as not to "interrupt anything the user is trying to do", allowing web applications to run alongside local software (similar to Mozilla Prism, Adobe AIR and Fluid).
