On Thursday Google Launched chrome 2, a purportedly faster and more feature-filled version of the search giant’s Web browser. Google chrome is directly competing with Internet explorer and Firefox for the browsing engine market. So whats so different about this upgrade , lets have a closer view:
New Features:
- Chrome 2.0 is faster than Version 1, released eight months ago, because it runs JavaScript faster, according to Google.
The extra speed comes from an update to its V8 JavaScript engine and from a new version of the open source WebKit rendering engine. However, Chrome’s speed advantage may soon be overshadowed by rivals. Mozilla , for example, is expected to release a final version of Firefox 3.5.
- It also incorporates some of the features beta testers requested the most. One is an improved new tab page that lets users remove thumbnails.
- Another is a new full-screen mode, and a third feature is form autofill.
However, full-screen mode and form autofill are both features other browsers (IE, Firefox) have been using for a while.
Need For Speed:
- The V8 JavaScript engine is open source technology developed by Google and written in C++. It increases performance by compiling JavaScript to native machine code before execution, instead of to a bytecode or interpretation.
- It also employs optimization techniques such as inline caching, which remembers the results of a previous method lookup directly at the call site. A call site of a function is a line in the code that passes arguments to the function and receives return values in exchange.
These optimizations let JavaScript applications run at the speed of a compiled binary.
Speed Thrills But Kills:
Supercharging JavaScript may not always result in a faster user experience.
“I’m not sure how big an impact speeding up JavaScript is going to make unless you’re using some huge JavaScript application,” ESET’s Abrams said.
Speeding up JavaScript could also speed up the malware based on the language.
“Malware based on JavaScript will run faster,” Abrams said. “JavaScript is the vector of choice for drive-by attacks.”
In a drive-by attack, a Web page containing malicious code downloads that code onto visitors’ computers without their knowledge or permission ,and without the user having to click on any links. Malware authors use JavaScript in almost 90 percent of Web pages that contain malicious script, according to Stephan Chenette, manager of security at Web security software vendor Websense.
Hackers Column:
No boys , it wont be easy to get in to chrome. The security is very tight this time around. Google spokesperson Eitan Bencuya told TechNewsWorld.
Sandboxing means isolating code so that it cannot interact with the operating system or applications on a user’s computer.
However, ESET’s Abrams says;
Chrome does have some protection other browsers don’t, in that it sandboxes individual tabs. That might protect the operating system itself, but it’s not going to do anything to protect you against cross-site scripting or clickjacking. It’s only effective if you go to each different site in a different tab. Otherwise, the old data will be accessible when you use the same tab to click on a new site
So what do you think, well only time will tell how the latest Chrome upgrade fair inthe competition. Thank you for listening, please give you views in the comments section.

sweet but do they really offer such a great new tab experience even with Chrome v.2? I’m staying with my beloved Firefox and the small add on from http://www.newtabking.com.
