Google’s New Browser ,, Will It Add Something !!

 

Before an hour, I went to google Main page and I found this new Browser called “Google Chrome”. Will this Browser be at the same level to compete with Windows Internet Explorer , Mozilla Firefox or even Apple Safari. We will see in the near future, But at the mean time, let us see the features of this new Browser :

as noted in Wikipedia :

Google Chrome is an open source web browser developed by Google.

 

 

 

Security

Blacklists

Chrome periodically downloads updates of two blacklists (one for phishing and one for malware) and warns users when they attempt to visit a harmful site. This service is also made available for use by others via a free public API called “Google Safe Browsing API”. In the process of maintaining these blacklists, Google also notifies the owners of listed sites who may not be aware of the presence of the harmful software.

Sandboxing

Each tab in Chrome is sandboxed to “prevent malware from installing itself” or “using what happens in one tab to affect what happens in another”. Following the principle of least privilege, each process is stripped of its rights and can compute but can’t write files or read from sensitive areas (eg documents, desktop), this is similar to “Protected Mode” that is used by Internet Explorer 7 on Windows Vista. The Sandbox Team is said to have “taken this existing process boundary and made it into a jail”; for example malicious software running in one tab is unable to sniff credit card numbers, interact with the mouse or tell “Windows to run an executable on start-up” and will be terminated when the tab is closed. This enforces a simple computer security model whereby there are two levels of multilevel security (user and sandbox) and the sandbox can only respond to communication requests initiated by the user.

Plugins

Plugins such as Adobe Flash Player are typically not standardised and as such cannot be sandboxed like tabs. These often need to run at or above the security level of the browser itself. To reduce exposure to attack, plugins are run in separate processes that communicate with the renderer, itself operating at “very low privileges” in dedicated per-tab processes. Plugins will need to be modified to operate within this software architecture while following the principle of least privilege.

Incognito

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.”

 

 

Speed

JavaScript

The Javascript virtual machine was considered a sufficiently important project to be split off (like Adobe/Mozilla’s Tamarin) and handled by a dedicated team in Denmark. Existing implementations were designed “for small programs, where the performance and interactivity of the system weren’t that important” but web applications like Gmail “are using the web browser to the fullest when it comes to DOM manipulations and Javascript”. The resulting V8 JavaScript engine was designed for speed and introduces new features with that in mind such as hidden class transitions, dynamic code generation, and precise garbage collection.Tests by Google show that V8 is about twice as fast as Firefox 3 and the Safari 4 beta.
