Google Chrome 14(4)

Security
PCMag’s security blogger, Larry Seltzer, considers Chrome path-breaking in a safety sense. The entire program architecture is internally sandboxed so that almost all vulnerabilities are unexploitable in any practical way. By integrating Flash, Google automatically updates it, which is certainly an important security advance, and as mentioned, that built-in plugin is now sandboxed in the Windows 7 and Vista versions of Chrome.

Verson 12 added still more Flash security, or rather, privacy: You can now manage data Flash Player’s Local Shared Objects, aka "Flash cookies" right from within the browser, rather than by visiting an Adobe Web page.Apple iBook G3 12inch バッテリー

Safe Browsing supplies the same kind of anti-malware and -phishing protections you’ll find in Firefox and IE9; you’ll even see a red warning page similar to Firefox’s if you try to surf onto a bad site. Chrome’s developers claim that Safe Browsing is now faster, more reliable, and uses the disk less often.

Following Internet Explorer’s lead, Chrome 12 further bolstered Safe Browsing with warnings when you start to download nefarious content. And Google claims to have built the feature in such a way that the search giant doesn’t have to know what sites you were visiting that generated warnings.

The browser supports SSL and can show Extended Validation SSL information, but it doesn’t support SSL client authentication, which lets developers authenticate users accessing the server by exchanging a client certificate. Chrome has also recently implemented some cross-site-scripting (XSS) protection in the Webkit rendering engine.

To help protect from crashes due to both malicious and poorly coded sites, Chrome runs each tab in a separate process. If a site on one tab freaks out, it won’t take down the whole browser. Chrome shares this approach with Internet Explorer, but Google’s browser takes the implementation a couple of welcome steps further, isolating plug-ins (such as Flash) as well as tabs and offering a Task Manager for your open tabs and add-ins. Firefox also isolates plug-in processes.

In addition to isolating simultaneous tab processes, Chrome does so sequentially: As you move to a different domain within a single tab, the browser throws out the earlier tab process and starts a new one, just in case the previous site caused memory leaks. I worried about the effect this would have on the Back button and whether the application would remember the session information from the earlier site, but I didn’t run into any problems during testing. I was able to check my webmail using the Back button even after moving to another site, for example.

All in all, at this point Chrome can comfortably stand up against any other browser on the basis of security.Acer AS09D31 ,FMV-BIBLO MG50U バッテリー , Dell PT434 ,Asus AL31-1015

Native Client
A major new capability in Chrome 14 is its support for a "Native Client" or "NaCl." This means programmers can write code in C or _C++ and have it run inside the browser. Most Web coding is done in JavaScript, which is much slower than native C code. Running native C code also means programmers can take advantage of existing C libraries for things like graphics and audio functions. Currently, only apps in the Chrome Web Store can use NaCl, but Google says that restriction will be lifted in the future. For security, NaCl apps are double sandboxed inside Chrome’s regular sandbox. Google’s hopes for Native Client echo those of Java from yesteryear: "write once, run everywhere." In other words, a programmer’s code will run on any platform that Chrome can run on, be that Windows, Mac, or Linux. Google’s Chrome blog claims that Chrome OS will be added to that list, which would seem a major reason for NaCl itself. Like a lot of Google initiatives, there’s a claim of "open standard" for the technology, but in reality, it’s likely to remain a Chrome-only option. In an excellent piece on Native Client, ExtremeTech’s Sebastian Anthony notes that Native Client is pretty much another plugin that detracts from a truly open Web, and resembles the denigrated ActiveX of years past. For now, there are only a couple Native Client demo apps. I tried a couple of these, the first of which just presented the "puzzle piece" icon and a message saying ‘The Native Client Plugin is not allowed." I had to type chrome://flags/ in the address bar, enable the feature, and then restart the browser to get the demos to work. A sign wave generator, a pi generator that randomly puts 1,000,000,000 points inside a square, and aGame of Life demo worked speedily. But all of these are things that existing Web technologies would have no trouble accomplishing, however.

Privacy
These days privacy is as big a concern as security. Chrome’s Incognito mode (much like IE8′s InPrivate feature) lets you move around the Web without leaving traces of your activity. As I’ve mentioned, you can use your extensions while in the mode. Chrome’s feature has an advantage over IE8′s in that you can have one tab in Incognito mode while viewing others in public mode. But the browser has no parental controls, so you’re on your own in policing your child’s Web use. And IE8 has its own big advantage: InPrivate actually prevents sites from seeing each other’s activity—something no other browser’s private mod offers.

After the FTC issued an advisory on Web activity tracking of consumers last year, most browser makers scurried to build features to protect them from these nosy advertisers. IE9 currently has the strongest anti-tracking feature among the big three browsers. Microsoft’s Tracking Protection is the only such tool that doesn’t require total buy-in from the potential trackers, as Firefox’s HTTP header solution and Google’s Keep My Opt-Outs extension do. Hopefully, the browser makers will make these tools more prominent and easier to enable.

Should Chrome Be Your Browser?
Chrome started the trend in simplifying the user interface and making it wickedly fast. It also continues to innovate, with things like Native Client, Audio API, Instant Pages, and built-in support for SPDY. While other browsers have mostly achieved parity in JavaScript performance, in HTML 5 support Google’s browser also maintains the lead. Google Chrome’s blazing speed, extension capability, excellent tab functionality, Instant feature, built-in Flash and PDF reading, and syncing capabilities make Chrome a delight to use. Because of all this, Chrome 14 remains our Editors’ Choice for Web browsers.COMPA nx7400バッテリー , VGP-BPS13A/Q , Toshiba PA3535U-1BAS , LENOVO L09C4P01
