Internet Browser: How good are the new Web browsers

The competition of the browser vendors Microsoft, Google and Mozilla is entering the next round - and this time win over the users: the new versions of Internet Explorer, Firefox and Chrome all have become faster and safer. The most important changes. They are faster, safer, and they look better than its predecessor: nearly the same time bring new versions of its leading web browser on the market - and there are three good Reasons to upgrade to one of the new. Last pre-release versions, so-called release candidates, there are both now available for download.


How good are the new Web browsers - an overview: More speed: all three manufacturers have improved the speed of your browser considerably. Firefox and Internet Explorer have to finally open to Chrome, but also has risen again. For many benchmark tests, build the programs in which pages or scripts and plug-ins, they must lie in about the same.

Especially when running JavaScript, the tempo increase is clearly noticeable. This was also an urgent need: from mail services via text to image editing programs, many complex web applications run directly from the browser. If Chrome is the new JavaScript compiler Crankshaft, improved JavaScript engine of Firefox, TraceMonkey, gets support from hunters monkey, and Microsoft's new JScript engine is named Chakra.

If possible, the browser will now fall back to hardware support for graphics computation. More security: Besides the usual improvements and corrections, there are some fundamental changes to the browser architecture: Chrome 10 has now the Flash plug-in the so-called sandbox shifted out the plug-in is, in a the rest of the system separated environment.

Attacks by malicious Flash applications to the bill, be in vain. According to Google, this was one of the biggest security holes in addition to outdated plug-ins by their developers are no longer maintained. The new Chrome will automatically disable. Even the Internet Explorer 9, the execution of plug-ins in a sandbox moved.

Mozilla's browser can run plug-ins for some time in separate processes. Also gives the Internet Explorer now to any open tab, open any website, its own computational process. Previously, shared by several sites a process. has used this technique with Google Chrome first consumes more memory initially, but ultimately the individual pages can be more responsive to inputs - especially if a plug-in or a script is hungry for resources or even crash.

While surfing is like the smart screen filter of the Internet Explorer web addresses from a database and warns against known phishing sites. The already known from the previous version feature has been improved again and is now also on trusted Web pages embedded with malicious code. Downloads are automatically scanned for malware.

Firefox does a better protection against attacks via cross-site scripting (CSS / XSS) with a. With a new standard, the HTTP transport Strict Security, Web sites can tell the browser in future to allow only encrypted connections. Man-in-the-middle attacks, where hackers intercept connections are to be prevented.

Less space for the Browser: The new browser left to the sites more valuable screen space. Program elements were reduced to the necessary minimum, Chrome led the way, now move to Firefox and Internet Explorer. Also in Firefox allows queries directly in the address line - is an additional search box on it anyway, Internet Explorer and Chrome without it.

The developers of Internet Explorer 9 are mighty proud that they make the browser virtually invisible - the focus should eventually lie in the content, not on the technology. Up to this realization, it took at least 16 years and competition from Google. The result is impressive, however.

Even Firefox, which with its 3-D effects and rounded edges and corners came along far more well, sees the new version of slim and slender. An exception is the Firefox menu, which is at least packed as the Windows Start menu. Internet Explorer and Chrome are limited to small menu in the right corner.

Google has moved its browser settings in a tab, the sub-menus can be directly accessed from the address bar (chrome: / / settings / advanced) search, and practical - this setting can be found quickly. All three browsers are trying to help their users to deal with a lot of open pages. Thus, for often "sticking" use tabs (Firefox, Chrome), or as a program put on the Windows taskbar (Internet Explorer).

Current Web standards: The new browser already support many of the new HTML5 features and related technologies, including CSS3 web fonts and WebGL. Even the Internet Explorer, decried years ago because of his idiosyncratic interpretation of standards among web developers keep to the basic rules.

The best cuts, however, from Google's Chrome. A quasi-standard does not, however Chrome: The Microsoft supported and Safari H.264 video codec. Instead, Google relies on its own codec - and Firefox is set to another, technically severed format. The HTML5 video support suffers so on to a missing codec for all - for now remains the first choice of Flash website owners.

Which browser do you prefer it? In any case, not the old man. The new browsers offer additional security and noticeable improvements in speed. Google's Chrome was in our test less wasteful with the memory to, at some older systems, this is a great advantage. Otherwise, try it says. Chrome and Firefox are also available for Mac OS X and Linux, only Internet Explorer is limited to Windows.

To whom any appeals of the three current browser, you can also resort to Opera 11 - the Norwegian manufacturer has overtaken its free browser, most recently in December. The major browser manufacturers have not copied only once technologies and operating concepts to Opera.
