Windows Internet Explorer 8: An Overview

Windows Internet Explorer 8(IE8) is a web browser developed by Microsoft in the Internet Explorer browser series for Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, and Windows 7. Both 32-bit and 64-bit builds are available.
It is the successor to Internet Explorer 7 and is the default browser for Windows 7 and Windows Server 2008 R2 operating systems.

Internet Explorer 8 is the first version of IE to pass the Acid2 test, and the last of the major browsers to do so, although it scores only 20/100 on the Acid3 Test. According to Microsoft, security, ease of use, and improvements in RSS, Cascading Style Sheets, and Ajax support were its priorities for IE8.

Internet Explorer 8 is the last version of Internet Explorer to be supported on Windows XP; the next version, Internet Explorer 9, is supported only on Windows Vista and Windows 7 operating systems

The added features include:

Accelerators

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. 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.

Accelerators eliminate the need to copy and paste content between web pages. IE8 specifies an XML-based encoding which allows a web application or web service to be invoked as an Accelerator service. The XML file specifies the service that will be invoked and for the categories of content it will show.

Autocomplete changes
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.

Automatic Tab crash recovery
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.

Developer tools

For developers, IE8 includes tools that allow HTML, CSS and JavaScript debugging directly from the browser.

Favorites Bar

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.

Inline search within pages
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.
