Windows Internet Explorer 8 (IE8) is a web browser for Windows. It was released by Microsoft on March 19, 2009, and is the default browser on Windows 7 and Windows Server 2008 R2. [3]
Internet Explorer 8 is the first version of IE to pass the Acid2 test, the last of the major browsers to do so. (In the later Acid3 Test, it only scores 24/100.) It is also the last version of Internet Explorer to support Windows XP SP2–SP3, Windows XP x64 Edition SP2, Windows Server 2003 SP2, Windows Vista RTM–SP1, and Windows Server 2008 RTM, as well as Itanium-based processors. [4] [5] Additionally, it introduced a Compatibility View mode to optionally emulate older versions' rendering behaviour, and color-coded tab groups where links opened in new tabs share the color of the website they originated from. [6] According to Microsoft, security, ease of use, and improvements in RSS, CSS, and Ajax support were its priorities for IE8. [7] [8]
IE8 development started in or before March 2006. [9] In February 2008, Microsoft sent out private invitations for IE8 Beta 1, [10] and on March 5, 2008, released Beta 1 to the general public, [11] although with a focus on web developers. [12] The release launched with a Windows Internet Explorer 8 Readiness Toolkit website promoting IE8 white papers, related software tools, and new features in addition to download links to the Beta. [11] [13] Microsoft Developer Network (MSDN) added new sections detailing new IE8 technology. [11] [14] Major press focused on a controversy about Version Targeting, and two new features then called WebSlice and Activities. The readiness toolkit was promoted as something "developers can exploit to make Internet Explorer 8 'light up'." [11]
On August 27, 2008, Microsoft made IE8 Beta 2 generally available. [15] PC World noted various Beta 2 features such as InPrivate mode, tab isolation and color-coding, and improved standards and compatibility compared to Internet Explorer 7. [16] Two name changes included Activities to Accelerators, and the IE7 Phishing filter renamed Safety Filter in the first Beta to SmartScreen, both accompanied by incremental technical changes as well. [16] By August 2008, the new feature called InPrivate had taken the spotlight. [16]
On January 5, 2009, a tool was provided by Microsoft to block the automatic install of Internet Explorer 8 via Windows Update.[ citation needed ]
IE8 reached general availability on March 19, 2009. A version optimized for Bing and MSN was also available. [17] [18]
Language support (localization) was not complete on release. IE8 was released with 25 languages. [19] This grew up to 63 for 32-bit in June 2009. [20] Support for additional languages can come pre-installed based on the OS, or downloaded and installed via Multilingual User Interface (MUI) packages. [21]

Support for IE8 on most supported Windows versions ended on January 12, 2016, when Microsoft began requiring customers to use the latest version of Internet Explorer available for each Windows version. [26] For versions of Windows in which IE8 was the final version of Internet Explorer available, support ended alongside the end of support for that version of Windows. This meant that support for IE8 on XP ended with its end of extended support on April 8, 2014. [27] On October 13, 2020, Microsoft released the final IE8 update for Windows Embedded Standard 7, marking the end of IE8 support on all platforms. [28]
IE8 contains many new features, including WebSlices and Accelerators. At the first glance, the most visible change of the user interface is that the tabs have an inward colour gradient instead of outward. [29] [30]
Accelerators are a form of selection-based search which allow a user to invoke an online service from any other page using only the mouse. [31] Actions such as selecting the text or other objects will give users access to the usable Accelerator services (such as blogging with the selected text, or viewing a map of a selected geographical location), which can then be invoked with the selected object. According to Microsoft, Accelerators eliminate the need to copy and paste content between web pages. [29] IE8 specifies an XML-based encoding which allows a web application or web service to be invoked as an Accelerator service. How the service will be invoked and for what categories of content it will show up are specified in the XML file. [32] Similarities have been drawn between Accelerators and the controversial Smart tags feature experimented with in the IE 6 Beta but withdrawn after criticism (though later included in MS Office). [12]
The address bar features domain highlighting for added security so that the top-level domain is shown in black whereas the other parts of the URL are grayed out. Domain highlighting cannot be turned off by users or web sites. Other features of the address bar include support for pasting multi-line URLs and an improved model for inserting the selection caret, and selecting words, or entire URLs in the Address bar. The inline autocomplete feature has been dropped from Internet Explorer 8, leading to criticism by beta users. [33]
If a website or add-on causes a tab to crash in Internet Explorer 8, only that tab is affected. The browser itself remains stable and other tabs remain unaffected, thereby minimizing any disruption to the browsing experience. If a tab unexpectedly closes or crashes it is automatically reloaded with the same content as before the crash.[ citation needed ]
For developers, Internet Explorer 8 includes tools that allow debugging HTML, CSS, JavaScript, and VBScript within the browser. [34]
Another new feature in IE8 is a redesigned Favorites Bar, which can now host content such as Web Slices, web feeds, and documents, in addition to website links.[ citation needed ]
Internet Explorer 8 now has replaced the Find... dialog box with an inline Find toolbar which can be activated by pressing Ctrl+F or from search box drop-down menu but the F3 (or any other kind of a keyboard-driven) NextFind command has gone. Internet Explorer 8 highlights all instances of found words while allowing the user to continue the navigation normally. [35]
A new security mode called InPrivate debuted with IE8, and consists of two main features: InPrivate Browsing and InPrivate Filtering. [16] InPrivate Browsing has been described as a "porn mode" in various news outlets. [36] [37] [38] [39] [40] [41] A similar feature, first introduced in Safari in 2005, [42] was later implemented in Firefox 3.5, Opera 10.5, and Google Chrome.
When a user uses InPrivate Browsing in Internet Explorer 8, one's browsing history, temporary Internet files, form data, cookies, and usernames and passwords are not retained by the browser, leaving no local evidence of browsing or search history.
InPrivate Filtering provides users an added level of control and choice about the information that third party websites can use to track browsing activity. InPrivate Subscriptions allow users to augment the capability of InPrivate Blocking by subscribing to lists of websites to block or allow.
As with other private browsing modes, there are ways that information about a browsing session can be recovered.
Internet Explorer 8 includes performance improvements across the HTML parser, CSS engine, mark-up tree manipulation as well as the JScript runtime and the associated garbage collector. Memory leaks due to inconsistent handling of circular references between JScript objects and DOM objects were corrected. [43] For better security and stability, IE8 uses the Loosely Coupled Internet Explorer (LCIE) architecture and runs the browser frame and tabs in separate processes. LCIE prevents glitches and hangs from bringing down the entire browser and leads to higher performance and scalability. Permissions for ActiveX controls have been made more flexible – instead of enabling or disabling them globally, they can now be allowed on a per-site basis. [44]
SmartScreen Filter extended Internet Explorer 7's phishing filter to include protection from socially engineered malware. Every website and download is checked against a local list of popular legitimate websites; if the site is not listed, the entire address is sent to Microsoft for further checks. [45] If it has been labeled as an impostor or harmful, Internet Explorer 8 will show a screen prompting that the site is reported harmful and shouldn't be visited. From there the user can either visit his or her homepage, visit the previous site, or continue to the unsafe page. [46] If a user attempts to download a file from a location reported harmful, then the download is cancelled. The effectiveness of SmartScreen filtering has been reported to be superior to socially engineered malware protection in other browsers. [47]
This feature can be disabled or enforced using Group Policy.
This feature is described by Microsoft as a tool to suggest websites, which is done by the browser sending information to Microsoft over a secure connection, which keeps the information and a per-session, uniquely generated identifier for a short time. [48] The Suggested Sites feature is turned off by default and is disabled when the user is browsing with InPrivate enabled or visiting SSL-secured, intranet, IP address, or IDN address sites. Information that could be personally identifiable, such as the user's IP address and browser information is sent to Microsoft as an artifact of the HTTPS protocol. Microsoft has stated that they do not store this information.
The functionality was defended by Microsoft after itworld.com's Gregg Keizer described it as a "phone home" feature. [49]
Web Slices are snippets of a full webpage to which a user can subscribe. [31] Web Slices are kept updated by the browser automatically, and can be viewed directly from the Favorites bar, complete with graphics and visuals. Developers can mark parts of the pages as Web Slices, using the hAtom
and hSlice
microformats. Web Slices have been compared to Active Desktop, introduced in Internet Explorer 4 in 1997. [50]
Microsoft donated the specification to the public domain under the Creative Commons Public Domain Dedication. It is also covered by the Microsoft Open Specification Promise. [51]
Windows RSS Platform also supports authenticated feeds beginning with Internet Explorer 8. [52]
Full-page zoom now reflows the text to remove the appearance of horizontal scrollbars on zooming. [44] Image scaling is done using bicubic interpolation resulting in smoother looking images when scaled. [53]
Using the Compatibility View mode will cause style issues with <select>
form elements when changing zoom levels.
The information bar lets users allow an ActiveX control to run on all Web sites or only the current one. Users can easily make changes to this behavior through the Manage Add-ons dialog box. For each ActiveX control, there's a list of sites where it has been approved by the user.
<wbr>
element is dropped. [57] Internet Explorer 8's main rendering mode, known as standards mode, has improved support for various web standards, especially CSS, compared to Internet Explorer 7 and earlier versions. [60]
The web standards supported by IE8 include the following:
getAttribute
, setAttribute
, and removeAttribute
modifiers have been changed to match the behavior of other browsers. [32] abbr
and elements [63] However, IE8 does not support some other W3C standards:
IE8 passes the Acid2 test, [65] [66] but fails the Acid3 test with a score of 24/100. During its development, Microsoft developed over 7,000 tests for CSS level 2 compliance, which were submitted to the W3C for inclusion in their test suite. [67]
Internet Explorer 8 was promoted by Microsoft as having stricter adherence to W3C described web standards than Internet Explorer 7. As a result, as in every IE version before it, some percentage of web pages coded to the behavior of the older versions would break in IE8. This would have been a repetition of the situation with IE7 which, while having fixed bugs from IE6, broke pages that used the IE6-specific hacks to work around its non-compliance. This was especially a problem for offline HTML documents, which may not be updatable (e.g., stored on a read-only medium, such as a CD-ROM or DVD-ROM).
To avoid this situation, IE8 implements a form of Version Targeting whereby a page could be authored to a specific version of a browser using the X-UA-Compatible
declaration either as a meta element or in the HTTP headers. [68]
In order to maintain backwards compatibility, sites can opt-into IE7-like handling of content by inserting a specially created meta element into the web page that triggers the "Compatibility View" mode in the browser, using: [60]
<metahttp-equiv="X-UA-Compatible"content="IE=EmulateIE7"/>
Five weeks after the release of IE8 Beta 2 in August 2008, Beta 1's market share had grown from 0.05 percent to 0.61 percent, according to Net Applications. [69] In July 2009, just under four months after the final release, the market share jumped to 13 percent. [70]
As of September 2013 [update] , estimates of IE8's global market share ranged from 6.93% to 8.73%. [71] [72] [73]
According to a Net Applications web analytics report from October 2014, Internet Explorer 8 accounted for 17.31% of web traffic, now overtaken by IE11 in usage.
In a March 19, 2009, review, Benny Har-Even of IT PRO offered some praise of Internet Explorer 8, noting its reliability and good features and concluding that it was "certainly the best version of Internet Explorer in a long time," but also that "there's not yet anything here to make Firefox users want to jump ship." [74] He offered praise to Microsoft for paying attention to their competition and producing "a better featured, faster and more reliable browsing experience for the masses" and suggested that as Microsoft continues to improve the product, it would become "harder to persuade the unconverted to switch away from IE." [74]
The next month, on April 2, Mark Joseph Edwards wrote in the newsletter Windows Secrets that the new edition of Internet Explorer had greatly improved security, speed, and compatibility, but opined that it still lagged behind competitors in all three areas. [75] Edwards noted that, at the time, Internet Explorer 8 was still underperforming relative to other browsers in speed and was not as successful in displaying webpages as they were intended to display as such browsers as Firefox and Opera. In terms of security, he wrote that its "continued reliance on ActiveX makes the browser vulnerable in its very foundation." [75] For these reasons, he suggested that Firefox remained a better alternative to Internet Explorer 8, even though it was a "much better browser than IE 7." [75]
Around 2010, a theme named "BlueSky" was created for the Mozilla Firefox browser with the aim to resemble the graphical user interface of Internet Explorer 8 as accurately as possible. [76] [77]

Internet Explorer is a retired series of graphical web browsers developed by Microsoft that were used in the Windows line of operating systems. While IE has been discontinued on most Windows editions, it remains supported on certain editions of Windows, such as Windows 10 LTSB/LTSC. Starting in 1995, it was first released as part of the add-on package Plus! for Windows 95 that year. Later versions were available as free downloads or in-service packs and included in the original equipment manufacturer (OEM) service releases of Windows 95 and later versions of Windows. Microsoft spent over US$100 million per year on Internet Explorer in the late 1990s, with over 1,000 people involved in the project by 1999. New feature development for the browser was discontinued in 2016 and ended support on June 15, 2022 for Windows 10 Semi-Annual Channel (SAC), in favor of its successor, Microsoft Edge.
This is a comparison of both historical and current web browsers based on developer, engine, platform(s), releases, license, and cost.
Trident is a proprietary browser engine for the Microsoft Windows version of Internet Explorer, developed by Microsoft.
Windows Internet Explorer 7 (IE7) is a version of Internet Explorer, a web browser for Windows. It was released by Microsoft on October 18, 2006. It was the first major update to the browser since 2001. It does not support versions of Windows earlier than Windows XP and Windows Server 2003.
Acid2 is a webpage that test web browsers' functionality in displaying aspects of HTML markup, CSS 2.1 styling, PNG images, and data URIs. The test page was released on 13 April 2005 by the Web Standards Project. The Acid2 test page will be displayed correctly in any application that follows the World Wide Web Consortium and Internet Engineering Task Force specifications for these technologies. These specifications are known as web standards because they describe how technologies used on the web are expected to function.
Microsoft developed 11 versions of Internet Explorer for Windows from 1995 to 2013. Microsoft also developed Internet Explorer for Mac, Internet Explorer for UNIX, and Internet Explorer Mobile respectively for Apple Macintosh, Unix, and mobile devices; the first two are discontinued but the latter runs on Windows CE, Windows Mobile, and Windows Phone.
Microsoft Internet Explorer 6 (IE6) is a web browser developed by Microsoft for Windows operating systems. Released on August 24, 2001, it is the sixth, and by now discontinued, version of Internet Explorer and the successor to Internet Explorer 5. It does not support earlier versions.
Microsoft Internet Explorer 5 (IE5) is the fifth, and by now, discontinued, version of the Internet Explorer graphical web browser, the successor to Internet Explorer 4 and one of the main participants of the first browser war. Its distribution methods and Windows integration were involved in the United States v. Microsoft Corp. case. Launched on March 18, 1999. Although Internet Explorer 5 ran only on Windows, its siblings Internet Explorer for Mac 5 and Internet Explorer for UNIX 5 supported Mac OS X, Solaris, and HP-UX.
Microsoft Internet Explorer 3 (IE3) is the third version of the Internet Explorer graphical web browser which was announced in March 1996, and was released on August 13, 1996 by Microsoft for Microsoft Windows and on January 8, 1997 for Apple Mac OS. It began serious competition against Netscape Navigator in the first Browser war. It was Microsoft's first browser release with a major internal development component. It was the first more widely used version of Internet Explorer, although it did not surpass Netscape or become the browser with the most market share. During its tenure, IE market share went from roughly 3–9% in early 1996 to 20–30% by the end of 1997. In September 1997 it was superseded by Microsoft Internet Explorer 4.
Microsoft Internet Explorer 2 (IE2) is the second, and by now discontinued, version of Internet Explorer (IE), a graphical web browser by Microsoft. It was unveiled in October 1995, and was released on November 27, 1995, for Microsoft Windows, and on April 23, 1996, for Apple Macintosh.
Internet Explorer Mobile was a mobile version of Internet Explorer developed by Microsoft, based on versions of the MSHTML (Trident) layout engine. IE Mobile comes loaded by default with Windows Phone and Windows CE. Later versions of Internet Explorer Mobile are based on the desktop version of Internet Explorer. Older versions however, called Pocket Internet Explorer, are not based on the same layout engine.
Conditional comments are conditional statements interpreted by Microsoft Internet Explorer versions 5 through 9 in HTML source code. They can be used to provide and hide code to and from these versions of Internet Explorer. Conditional comments are not supported in Internet Explorer 10 and 11.
The Acid3 test is a web test page from the Web Standards Project that checks a web browser's compliance with elements of various web standards, particularly the Document Object Model (DOM) and JavaScript.
Internet Explorer 9 or IE9 is the ninth major version of the Internet Explorer web browser for Windows. It was released by Microsoft on March 14, 2011, as the successor to Internet Explorer 8. Microsoft released Internet Explorer 9 as a major out-of-band version that was not tied to the release schedule of any particular version of Windows, unlike previous versions. It is the first version of Internet Explorer not to be bundled with a Windows operating system, although some OEMs have installed it with Windows on their PCs. Internet Explorer 9 was the last version to be called Windows Internet Explorer. The software was rebranded simply as Internet Explorer starting with the release of Internet Explorer 10.
Internet Explorer is a series of graphical web browsers developed by Microsoft and included as part of the Microsoft Windows line of operating systems, starting in 1995.
Web Slices are a web feed technology based on the hAtom Microformat that allows users to subscribe to portions of a web page. Microsoft developed the Web Slice format, and published a specification under their Open Specification Promise. The specification is not published by any independent standards body. Introduced in Internet Explorer 8 Beta 1, Web Slices can be previewed in a fly-out window. As of 2012, Internet Explorer 8 and 9 were the only browsers to support Web Slices natively, although Mozilla Firefox had support via an add-on called webchunks.
Accelerators were a form of selection-based search allowing a user to invoke an online service from any other page using only the mouse; they were introduced by Microsoft in Internet Explorer 8. Actions such as selecting the text or other objects gave users access to the usable Accelerator services, which could then be invoked with the selected object. According to Microsoft, Accelerators eliminated the need to copy and paste content between web pages. IE 8 specified an XML-based encoding which allowed a web application or web service to be invoked as an Accelerator service. How the service would be invoked and for what categories of content it would show up were specified in the XML file. Similarities have been drawn between Accelerators and the controversial smart tags feature experimented with in the IE 6 Beta but withdrawn after criticism.
Internet Explorer 10 (IE10) is the tenth, and by now, discontinued, version of the Internet Explorer web browser and the successor to Internet Explorer 9, released by Microsoft on September 4, 2012. It is the default browser on Windows 8 and Windows Server 2012, and was later made available for Windows 7 and Windows Server 2008 R2. It does not support Windows Vista, Windows Server 2008, or earlier versions.
A compatibility mode is a software mechanism in which a software either emulates an older version of software, or mimics another operating system in order to allow older or incompatible software or files to remain compatible with the computer's newer hardware or software. Examples of the software using the mode are operating systems and Internet Explorer.
Internet Explorer 11 (IE11) is the eleventh and final version of the Internet Explorer web browser. It was initially included in the release of Windows 8.1, Windows RT 8.1 and Windows Server 2012 R2 on October 17, 2013, and was later released for Windows 7 and Windows Server 2008 R2 on November 7, 2013. It is the successor to Internet Explorer 10, released the previous year, and was the original, default browser in Windows 8.1 and Windows Server 2012 R2, before Microsoft Edge was introduced. Internet Explorer 11 was also included in the release of Windows 10 on July 29, 2015, as well as in Windows Server 2016 and Windows Server 2019. On April 16, 2019, Internet Explorer 11 was made available to Windows Server 2012 and Windows Embedded 8 Standard, the only still supported edition of Windows 8 as the final expansion of Internet Explorer 11 availability. Internet Explorer 11, like its predecessor, is not available for Windows 8, Windows Vista, Windows Server 2008, and earlier versions of Windows and Windows Server.
