Mozilla Firefox

Mozilla Firefox is a free and open source web browser developed for Microsoft Windows, Mac OS X, and Linux coordinated by Mozilla Corporation and Mozilla Foundation.

Firefox uses the Gecko layout engine to render web pages, which implements current and anticipated web standards.

As of May 2012, Firefox has approximately 25% of worldwide usage share of web browsers, making it the third most widely used web browser.

The browser has had particular success in Indonesia, Germany and Poland, where it is the most popular browser with 67%, 50% and 44% of the market share respectively.

The Firefox project began as an experimental branch of the Mozilla project by Dave Hyatt, Joe Hewitt and Blake Ross.

They believed the commercial requirements of Netscape's sponsorship and developer-driven feature creep compromised the utility of the Mozilla browser.

To combat what they saw as the Mozilla Suite's software bloat, they created a stand-alone browser, with which they intended to replace the Mozilla Suite.

On April 3, 2003, the Mozilla Organization announced that they planned to change their focus from the Mozilla Suite to Firefox and Thunderbird.

The Firefox project has undergone several name changes.

Opera 10

Opera 10 is a version of the Opera web browser.

This release added a variety of new features, a new skin designed by Jon Hicks, increased standards support, and a new application icon to Opera.

Opera 10.00 was touted as being 40% faster than Opera 9.6, with the upgrade of Opera's rendering engine to Presto 2.2.15.

In comparison to 9.x versions, Opera 10.50 uses Presto 2.5.22 which improves rendering speed, adds support for web standards such as RGBA/HSLA color, border-radius, and CSS transitions, and improves existing support for web standards.

Opera 10 automatically detects when a connection is slow, and offers to compress web pages via Opera Software's Turbo servers, thus reducing download size.

Opera Turbo could also be used to access websites that are blocked on a school or work network, because the browser sends the request to the Opera servers when using this feature, preventing the network from understanding which website it is trying to access.

Opera 10 introduces the ability to author HTML email in Opera's mail client.

As many older websites only detect the first character in the browser version, Opera 10 would be detected as Opera 1.

Originally it was planned to release Unite in Opera 10.00, however its release was delayed until Opera 10.10 to allow further stabilization.
Linux skipped 10.5× altogether, meaning the release of Opera 10.60 brings Windows, Mac, Linux and FreeBSD releases back into sync for the first time since Opera 10.10.


IBrowse is an MUI-based web browser for the Amiga range of computers, and was a rewritten follow-on to Amiga Mosaic, one of the first web browsers for the Amiga Computer.

IBrowse was originally developed for a company called Omnipresence, now defunct.

A limited OEM version of IBrowse is included with AmigaOS 4. IBrowse has not been available for sale to new customers since April 2007 when their distributor quit Amiga market, although existing v2.x users can download and install the demo version over their existing installation in order to access all functionality.

Internet Explorer 9

Windows Internet Explorer 9 (abbreviated as IE9) is the current version of the Internet Explorer web browser from Microsoft.

The system requirements for Internet Explorer 9 are Windows 7, Windows Server 2008 R2, Windows Vista Service Pack 2 or Windows Server 2008 SP2 with the Platform Update.

Internet Explorer 9 is the last version of Internet Explorer to be supported on Windows Vista; Internet Explorer 10 will only be supported on Windows 7 and later.

The Internet Explorer team also introduced the new JavaScript engine for 32-bit Internet Explorer 9, codenamed Chakra, which uses Just-in-time compilation to execute JavaScript as native code.

In mid-September 2011, the Acid3 test was revised to remove a few "antiquated and unusual" tests and as a result IE9 now passes the test with a score of 100/100 At MIX 10, the first Internet Explorer 9 Platform Preview was released, which featured support for CSS3 and SVG, a new JavaScript engine called Chakra, and a score of 55/100 on the Acid3 test, up from 20/100 for Internet Explorer 8. On May 5, 2010, the second Internet Explorer 9 Platform Preview was released, which featured a score of 68/100 on the Acid3 test and faster performance on the WebKit SunSpider JavaScript benchmark than the first Internet Explorer 9 Platform Preview.

On June 23, 2010, the third Internet Explorer 9 Platform Preview was released, which featured a score of 83/100 on the Acid3 test and a faster JavaScript engine than the second Internet Explorer 9 Platform Preview.
On August 4, 2010, the fourth Internet Explorer 9 Platform Preview was released, which features a score of 95/100 on the Acid3 test and a faster JavaScript engine than the third Internet Explorer 9 Platform Preview.

The Internet Explorer 9 implementation report, which was created using Internet Explorer 9 Beta, shows Internet Explorer 9 passing 97.7% of all tests on the W3C CSS 2.1 test suite.

Microsoft has been a part of creating this format during the development of Internet Explorer 9. Internet Explorer 9 includes a Tracking Protection feature which improves upon Internet Explorer 8's InPrivate Filtering.

Safari (web browser)

A version of Safari for the Microsoft Windows operating system, first released on June 11, 2007, supports Windows XP, Windows Vista, and Windows 7. According to Net Applications, Safari accounted for 62.17 percent of mobile web browsing traffic and 5.43 percent of desktop traffic in October 2011, giving a combined market share of 8.72 percent.

Microsoft ultimately released a Mac OS X edition of Internet Explorer for Mac, which was included as the default browser in all Mac OS X releases from Mac OS X DP4 up to and including Mac OS X v10.2.

Initially only available as a separate download for Mac OS X v10.2, it was included with the Mac OS X v10.3 release on October 24, 2003 as the default browser, with Internet Explorer for Mac included only as an alternative browser.
On June 11, 2007, at the Apple Worldwide Developers Conference, Jobs announced Safari 3 for Mac OS X v10.5, Windows XP, and Windows Vista.

Apple released Safari 5 on June 7, 2010, featuring the new Safari Reader for reading articles on the web without distraction (based on Arc90's Readability tool), and a 30 percent Javascript performance increase over Safari 4. Safari 5 includes improved developer tools and supports more than a dozen new HTML5 technologies, focused on interoperability.

Apple simultaneously released Safari 5.06 for Mac OS X 10.5 Leopard, excluding Leopard users from the new functions in Safari 5.1.
Beginning with Safari 4, the address bar has been completely revamped: These modifications make Safari on Mac OS X and Windows look more similar to Safari on iPhone than previous versions.

Safari 5.1 requires either a Mac running Mac OS X v10.6.8, or a PC running Windows XP SP2, Windows Vista, or Windows 7. Official minimum hardware requirements for Windows state a 500 MHz Pentium processor with 256 MB of RAM for Windows.

An earlier version of Apple Software Update (bundled with Safari, QuickTime, and iTunes for Microsoft Windows) selected Safari for installation from a list of Apple programs to download by default, even when a pre-existing installation of Safari was not detected on a user's machine.

The original software license agreement for Safari on Windows was unusually restrictive for several months, reading in part: As most personal computers running Windows are not Apple-labeled computers, it was impossible for most Windows users to use the software and abide by the license agreement, with the exception of Intel-based Mac computers running Windows.

Google Chrome

Google Chrome is the basis of Google's Chrome OS operating system that ships on specific hardware from Google's manufacturing partners.

Mozilla said that Chrome's introduction into the web browser market comes as "no real surprise", that "Chrome is not aimed at competing with Firefox", and furthermore that it would not affect Google's revenue relationship with Mozilla.

On January 11, 2011 the Chrome Product manager, Mike Jazayeri, announced that Chrome will no longer support H.264 video codec for its HTML5 player, citing the desire to bring Google Chrome more inline with the currently available open codecs available in the Chromium project, which Chrome is based on.

The normal downloaded Chrome installer puts the browser in the user's local app data directory and provides invisible background updates, but the MSI package will allow installation at the system level, providing system administrators control over the update process – it was formerly possible only when Chrome was installed using Google Pack.

Chromium, unlike the pre-release versions of Chrome, is updated almost every day, but does not include the built-in Flash Player (it has to be downloaded separately) and Google Auto-updater found in Chrome.
However Chrome was the first browser to to be defeated at Pwn2Own 2012, by a French team who used zero day exploits to take complete control of a fully patched 64-bit Windows 7 PC using a booby-trapped website that overcame Chrome's sandboxing.

The company stated that usage metrics are only sent when users opt in by checking the option "help make Google Chrome better by automatically sending usage statistics and crash reports to Google" when the browser is installed.
They unanimously reported that Chrome performed much faster than all competitors against which it had been tested, including Safari (for Windows), Firefox 3.0, Internet Explorer 7, Opera, and Internet Explorer 8. However in more recent independent tests of JavaScript performance, Chrome has been scoring just behind Opera's Presto engine since it was updated in version 10.5.

Chrome utilizes the faster, SPDY protocol instead of HTTP when communicating with Google services, such as Google Search, Gmail, Chrome sync and when serving Google's ads.

The Chrome Web Store was opened on February 11, 2011 with the release of Google Chrome 9.0.
