First Look: Firefox 4 Web browser Review | Browsers & Add-Ons | Macworld



First Look: Firefox 4 Web browser Review | Browsers & Add-Ons | Macworld

For years, Firefox has trundled along at the back of the browser pack, a beast of burden laden with fancy features but lacking speed. Not anymore. Mozilla has released Firefox 4, and in our preliminary tests, the browser makes a huge performance leap forward.

On a 2GHz Core 2 Duo aluminum MacBook with 2GB of RAM, Firefox 4 roughly quadrupled Firefox 3.6.15’s speed in an XHTML rendering test and the SunSpider JavaScript benchmark. Its Acid3 score improved by 3 points (reaching 97 out of 100), and it gained more than 100 points out of 400 on its predecessor in an HTML5 compliance test (255 and 9 bonus points vs. 155 and 4 bonus points).

Against other browsers, Firefox 4’s XHTML and CSS rendering speed still trails the latest versions of Safari, Opera, and Chrome, and it lacks their perfect Acid3 scores. But its HTML5 compliance outscores Safari’s and Opera’s, and only slightly lags Chrome’s, and in the SunSpider test, Firefox 4’s JägerMonkey JavaScript engine beats everyone else.

Firefox 4 packs a few other happy improvements under the hood. It now offers full support for CSS3 transforms and transitions, and hugely enhanced support for CSS3 animations. Built-in hardware acceleration vastly speeds up page rendering; however, in a Mozilla-created “stress test,” my computer and browser only eked out 2 frames per second when attempting 3D transformations on multiple 2D images. Firefox 4’s superb support for WebGL 3D graphics, Google’s new WebM open source video codec, and OpenType font rendering left me much more impressed.

Firefox 4’s interface changes are a somewhat mixed bag. Tabs now top the URL bar, Chrome-style, and you can now jump directly to a tab by starting to type its name in the “awesome bar” –nice, but nothing major. I liked the “app tab” feature, which lets you shift Gmail, Google Docs, and other much-used Web apps into tiny, space-saving icon tabs at the far left of the tab list.

The ability to group tabs by dragging and dropping left me cold, though. You must switch to an entirely separate screen, and drag tabs one by one into groups. The whole process just added an extra layer of clutter and confusion to my browsing.

We’re working on a full review of Firefox 4. For now, Firefox 4 looks like a happy compromise between speed-demon performance and a polished interface.

Browsers pick up the pace (week in review) | Business Tech - CNET News

Browsers pick up the pace (week in review) | Business Tech - CNET News



It might seem like the tech news this week has been all about the new iPad, but speedier browser versions grabbed some big headlines as well.
Google on Tuesday released Chrome 10, endowing its browser with faster JavaScript, password synchronization, and a revamped preferences system. Chrome is available for Windows, Mac, and Linux.

Google announced Chrome 10's stable release on its blog but refrained from mentioning its product number. That's in line with the company's effort to focus on features rather than version numbers, which it calls mere milestones. Google tries to get new versions into users' hands as rapidly as possible and currently passes a new milestone about once every six weeks.

Chrome 10 comes with the "Crankshaft" version of the V8 browser engine that Google pegs as 66 percent faster than the unnamed version in Chrome 9 as measured with Google's V8 Benchmark suite. That's a major speed boost, but be aware there are many other attributes of browser performance, and one of the biggest--hardware acceleration--will hit prime time with the imminent release of Mozilla's Firefox 4 and Microsoft's Internet Explorer 9.
Speaking of IE9, Microsoft will be formally launching the next version of its browser at the South by Southwest Interactive Festival on Monday--an interesting place to launch, given that the Austin, Texas, geek fest is packed full of the hordes who have long since ditched Internet Explorer for the decidedly hipper pastures of Firefox, Safari, or Chrome.

Among the new features in IE9 is a refreshed look with the browser taking up less space than previous versions of IE, as well as a way to pin sites to the Windows task bar. Sites can then program their pages to act more like desktop applications with things like notifications, and the Windows 7 Jump List feature, which can hop users to specific parts of a Web page.

IE9 also brings performance improvements, including faster start times and a new JavaScript engine called Chakra that Microsoft has proven to be faster at the WebKit SunSpider benchmark test than competitors. On the security side, IE9 also adds support for "do not track" through lists that users can subscribe to, as well as a way to filter ActiveX content from pages.

Meanwhile, Mozilla updated the Firefox 4 beta to release candidate status, meaning that the features are locked, and barring the discovery of any major bugs, this version is likely to become the browser's official release. Available to download for Windows, Mac, and Linux, Firefox 4 release candidate 1 contains no major bug fixes, and instead offers a series of stability, compatibility, and performance tweaks.

Google Chrome 10's New Settings Menu



The best browser in the world has gotten even better. It is sven much faster than version 9. Google Chrome has been updated 6 times since May of 2010. Those folks who still naively use Internet Explorer have not sen an update of that terrible browser in over three years. If you still use Internet Explorer download Chrome and you will be shocked by what you have been missing.

Google Chrome 10 focuses on speed and security

n keeping with its promise to update the Chrome browser every six weeks, Google rolled out Chrome 10 today. The new browser offers big boosts in speed and a host of new security features.

Speed is a main focal point in the ongoing browser wars, so naturally, Chrome 10 needs to ratchet up its quickness quotient -- and it does. Thanks to the Crankshaft JavaScript engine, Chrome 10 boosts JavaScript performance 66 percent, according to the V8 benchmark suite.

On the security front, Google has extended Chrome's sandbox to include the integrated Flash Player. The new browser also features malware reporting and will automatically disable out-of-date versions of plug-ins in order to thwart potential exploits.

Additionally, Chrome sports usability upgrades, including a new Browser Settings interface that is a tab in the browser instead of being a separate box. Alternately, settings can be found via a new search box that shows users the settings they're looking for as they type (typing "import" into the search bar will bring up the Import Bookmarks button, for example). Chrome Sync, for synchronizing passwords among different computers, is now turned on by default, and the browser sports GPU-accelerated video to cut down on CPU usage.

Chrome 10 is already available for download, and auto-updates of old Chrome browsers will begin soon, according to Google.

Browser Feature War: IE9 RC1 vs. Firefox 4 vs. Chrome 9 - PCWorld

Browser Feature War: IE9 RC1 vs. Firefox 4 vs. Chrome 9 - PCWorld



The browser wars are back with a vengeance.

Microsoft recently launched its first release candidate for Internet Explorer 9 (IE9 RC1), which features hardware acceleration, a simplified interface, Windows 7 jump lists, and a new "do not track" feature.

Not to be outdone, Google Chrome 9, which launched earlier this month, is sporting 3D hardware acceleration, Google Instant Search, and the Chrome Web Store. Meanwhile, Firefox 4 is in on its one-millionth beta (just kidding, it's on beta 11), rocking its own online tracking opt-out mechanism, an updated interface, and WebGL hardware acceleration.

It's a browser battle for the ages. But watch out Chrome and Firefox, the Borg (that was Microsoft's pet name in the 90's, kids) are back and this time resistance really is futile. Let's take a look.

Don't Follow Me

The Federal Trade Commission has been clamoring for Web browsers to institute do not track features that tell online advertisers you don't want them to follow you around while you browse the Web. Internet Explorer 9 has answered that call with a new feature called Tracking Protection. IE9's do not track feature allows you to create lists of sites that you want to block from tracking you. You can created your own list or find some pre-defined lists here on Microsoft's IE9 Website. To enable Tracking Protection in IE9, click on the settings cog in the upper right corner of IE9 RC1 then select Safety>Tracking Protection.

Firefox's answer to tracking is much simpler. The browser has simply instituted a system that puts a message in your browser's metadata that tells Websites you visit that you don't want to be tracked. Of course, it's any body's guess if the sites you visit will honor your request, but it's still a simple and elegant approach. To turn on Firefox 4's do not track feature in Windows 7 go to the Firefox tab in the upper left corner then click Options>Options>Advanced. Then under "Browsing" select "Tell web sites I do not want to be tracked." ??Chrome also has a do not track feature that you can activate by downloading an add-on called "Keep My Opt-outs."

Click to ZoomSimplified Interface

Firefox 4's new look is pretty much the same as it has been since Firefox 4's first beta came out in the middle of last year. Windows Vista and 7 users will see a new orange button in the upper left corner of the browser that houses most of Firefox's menu items. The home button and favorites can be found on the far right side of the browser window. Firefox also has tabs on top similar to Chrome's approach. This means you have less browser to deal with and more room to view the actual Web page.

Click to ZoomInternet Explorer also joined the Chrome-style revolution with IE9 RC1. The toolbar has been shaved down and the tabs have been put on the same line as the URL address bar to maximize the space for Web page views. The downside is that multiple tabs quickly go off the screen in IE9. You can change this by right-clicking any tab and selecting "Show tabs on a separate row." This will move your tabs to a separate row from the URL address bar, but it will cost you a tiny fraction of Web page viewing space.

In my advanced tests (by putting my finger on the screen), I determined that all three browsers now have pretty much the same screen space for viewing Web pages when you run them without toolbars.

Hardware Acceleration

All three browsers are focused on improving browser speeds. Internet Explorer 9 RC1 uses its own brand of hardware acceleration designed to take advantage of multiple processor cores as well as optimizing the power of your machine's graphics processing unit (GPU). IE9 RC1 also uses special Windows APIs to improve performance for 3D graphics, and has an improved JavaScript engine.

Both Chrome and Firefox use a Web standard called WebGL that speeds up the performance of online 3D graphics without the use of plug-ins. Firefox 4 also has a new JavaScript engine called JägerMonkey to improve speed performance. The latest Firefox beta build also uses hardware acceleration to improve speeds.

During my browsing session with each browser, IE9 appeared to react a little faster than both Firefox and Chrome by about two seconds. But we'll have to wait for PC World's official tests to get a better idea of which browser is actually faster.

Chrome Web Store and Instant

Google Chrome users in the United States now have access to the Chrome Web Store in Chrome 9. Just click on "Chrome Web Store" when you open a new tab to check out all the Web-based apps you can subscribe to or try out for free. You can check out this run down of 10 cool Web apps to get started.

Click to ZoomYou can also use Google Chrome 9's new search feature, Instant, that shows you web pages as you type and tries to predict just what you're looking for. To turn on instant in Chrome go to click on the wrench icon in the upper right corner and select "Options." Then select the check box that says "Enable Instant for faster searching and browsing."

Jump Lists

For Windows 7 users IE9's pinned Websites can be very handy. If you want to have easy access to sites you visit on a regular basis just drag the site's tab from IE9 into your Windows taskbar to pin it there. This will allow you to open the site in its own browser window with just one click. Some sites are also taking advantage of IE9's jump list feature that give you quick access to specific parts of the site. PC World's IE9 jump lists give you quick access to News, Reviews, Business Center, App Guide and How To sections. You can find out if a site has jump lists by right-clicking the pinned site's icon in your taskbar.

So which browser is best? Well, choosing a browser is more about your own personal taste than anything else. Internet Explorer may not be the dominant browsing force it once was, but with improved performance and a few handy features, it is well worth a look. Can it regain its once dominant position in the browser market with plus 90 percent share? It certainly has a long way to go from its current position of about 56 percent share, according to recent numbers from Net Applications. But IE9 RC1 is an impressive browser and just might let Microsoft dominate the Web browsing market once more. Like I said, the Borg are back baby, and this time you will be assimilated.
