Google Chrome is a browser that combines a minimal design with sophisticated technology to make the web faster, safer, and easier. Google
Chrome comes with a full range of competitive features, and is among
the most standards-compliant and fastest browsers available. Chrome's
minimalist interface, fast page-load times, and support for extensions
make the browser appealing to the average user as well as to Google
fanatics.
• Sandboxing. Every tab in Chrome is sandboxed, so that a tab can display contents of a web page and accept user input, but it will not be able to read the user’s desktop or personal files.
Google say they have “taken the existing process boundary and made it into a jail”. There is an exception to this rule; browser plugins such as Adobe Flash Player do not run within the boundaries of the tab jail, and so users will still be vulnerable to cross-browser exploits based on plugins, until plugins have been updated to work with the new Chrome security. Google has also developed a new phishing blacklist, which will be built into Chrome, as well as made available via a separate public API.
• Privacy. Google announces a so-called incognito mode claiming that it “lets you browse the web in complete privacy because it doesn’t record any of your activity”. No features of this, and no implications of the default mode with respect to Google’s database are given.
• Speed. Speed improvements are a primary design goal.
Stability
• Multiprocessing. The Gears team were considering a multithreaded browser (noting that a problem with existing web browser implementations was that they are inherently single-threaded) and Chrome implemented this concept with a multiprocessing architecture. A separate process is allocated to each task (eg tabs, plugins), as is the case with modern operating systems. This prevents tasks from interfering with each other which is good for both security and stability; an attacker successfully gaining access to one application does not give them access to all and failure in one application results in a “Sad Tab” screen of death. This strategy exacts a fixed per-process cost up front but results in less memory bloat overall as fragmentation is confined to each process and no longer results in further memory allocations. To complement this, Chrome will also feature a process manager which will allow the user to see how much memory and CPU each tab is using, as well as kill unresponsive tabs.
User interface
• Features. Chrome has added some commonly used plugin-specific features of other browsers into the default package, such as an Incognito tab mode, where no logs of the user activity are stored, and all cookies from the session are discarded. As a part of Chrome’s javascript virtual machine, pop-up javascript windows will not be shown by default, and will instead appear as a small bar at the bottom of the interface until the user wishes to display or hide the window. Chrome will include support for web applications running alongside other local applications on the computer. Tabs can be put in a web-app mode, where the omnibar and controls will be hidden with the goal of allowing the user to use the web-app without the browser “in the way”.
• Rendering Engine. Chrome uses the WebKit rendering engine on advice from the Gears team because it is simple, memory efficient, useful on embedded devices and easy to learn for new developers.
• Tabs. While all of the major tabbed web browsers (e.g. Internet Explorer, Firefox) have been designed with the window as the primary container, Chrome will put tabs first (similar to Opera). The most immediate way this will show is in the user interface: tabs will be at the top of the window, instead of below the controls, as in the other major tabbed browsers. In Chrome, each tab will be an individual process, and each will have its own browser controls and address bar (dubbed omnibox), a design that adds stability to the browser. If one tab fails only one process dies; the browser can still be used as normal with the exception of the dead tab. Chrome will also implement a New Tab Page which shows the nine most visited pages in thumbnails, along with the most searched on sites, most recently bookmarked sites, and most recently closed tabs, upon opening a new tab, similar to Opera’s “Speed Dial” page.
What's New On Google Chrome 44?
The Chrome team is excited to announce the promotion of Chrome 44 to the beta channel for Windows, Mac and Linux. Chrome 44.0.2403.157 contains many improvements including:

Speed
- Chrome is designed to be fast in every possible way: It's quick to start up from your desktop, loads web pages in a snap, and runs complex web applications fast .
Simplicity
- Chrome's browser window is streamlined, clean and simple.Chrome also includes features that are designed for efficiency and ease of use. For example, you can search and navigate from the same box, and arrange tabs however you wish quickly and easily.
Security
- Chrome is designed to keep you safer and more secure on the web with built-in malware and phishing protection, autoupdates to make sure the browser is up-to-date with the latest security updates, and more.
And more features
- Chrome has many useful features built in, including extensions, translation in the browser, themes, and more.

What's New On Google Chrome 44?
The Chrome team is excited to announce the promotion of Chrome 44 to the beta channel for Windows, Mac and Linux. Chrome 44.0.2403.157 contains many improvements including:
- A new cadence based rendering algorithm that improves video rendering in Chrome. Users should see much smoother video playback in Chrome for all video content. However, this is especially beneficial for the cases where the system was on the border of playing back certain videos. For example, users who previously had minor stuttering with high resolution or high frame rate content (4k, 1080p60) should now have a smooth playback experience.
- Lots of under the hood changes for stability and performance.
