What You Need to Know About Microsoft Internet Explorer 8.0 Features

With the Beta 2 release of Microsoft Internet Explorer (IE) 8.0 delivered to customers in August 2008, Microsoft is on track to ship the final version of its next browser. IE 8.0 delivers on the key tenets of its predecessor, IE 7.0, with advances around day-to-day usage, trustworthy computing and safety, and developer features. But IE 8.0 also includes the biggest technological break with the past yet seen in Microsoft’s browser platform: Unlike previous versions, IE 8.0 will render web pages in a standardscompliant mode that’s similar to how browsers such as Mozilla Firefox render web pages, a change that could lead to compatibility issues for businesses. Here’s what you need to know about IE 8.0.

Improved Browsing
With the industry moving to a cloud computing model where more and more of our work is performed through the web browser, products such as IE are more important than ever before. This increased reliance on the web requires new levels of performance, reliability, and functionality, and, for the enterprise, suitability for missioncritical applications, manageability, and compatibility.

From a raw performance standpoint, Microsoft has tweaked IE 8.0 to make it perform faster. The browser starts up quicker than its predecessor, as do new tabs and secondary windows. Sites with JavaScript will run more quickly as well, Microsoft says, thanks to an overhauled JavaScript parser. Microsoft has also dramatically improved memory management.

Dean Hachamovitch, Microsoft’s general manager for the Internet Explorer team, told me that the performance improvements in IE 8.0 go well beyond pure benchmarks, however. “With IE 8.0, the sum is greater than the parts,” he said. “We’ve looked holistically at how users actually use the browser. And we’ve made sure that IE 8.0 performs better in day-to-day use, making users more efficient and placing them in control.”

To this end, IE 8.0 includes hundreds of improvements and small efficiencies. “Accelerators” pop up as needed, giving users contextsensitive actions (formerly called “Activities” in IE 8.0 Beta 1), while “Web Slices,” also introduced in Beta 1, provide a way for users to subscribe to portions of web pages that change frequently. (To learn more about IE 8.0 Beta 1, see “What You Need to Know About Microsoft Internet Explorer 8.0 Beta 1,” InstantDoc ID 98795.)

The new IE 8.0 Smart Address Bar presents an organized dropdown list that changes as you type, providing you with quick access to your relevant browser history, Favorites, and subscribed RSS feeds. And if one of the search results contains a typo, you can now remove it from your history and thus any future search results. “Our research shows that 80 percent of navigation is to previously visited places,” Hachamovitch said.

Tabs, a strong point in IE 7.0, become more intelligent and useful in IE 8.0, which automatically collects related tabs into groups, each of which has its own color scheme. Thus, when you CTRL-click on a link on the current page, the new tab opens next to that tab, and not at the end of the list of tabs; the two tabs also match in color.

“This seems like a small thing, but it’s important,” Hachamovitch told me. “Tabs open near their source and are grouped according to what the user is doing. They’re not just a bunch of tabs, because the user has a task in mind.”

And if you open a blank new tab, you’re presented with a useful UI that provides access to lists of recently closed tabs (in case you mistakenly closed something important), Accelerators, and other features. You can also bookmark a tab group and then display the group as tabs again later.

Answering one of my long-standing complaints about IE, Microsoft has finally replaced the Find dialog box—which could often obscure the content on the very page you were trying to search—with a new Find On This Page toolbar that appears right below the tabs and Command Bar in the browser’s UI. This toolbar offers the option of highlighting search results and works much like a similar feature in Mozilla Firefox. (Now if Microsoft would only add a similar feature to its Office applications, they’d really be on to something.)

The IE 8.0 search box has been dramatically improved, and it applies whether you use Microsoft’s Live Search engine or not. The box provides a plug-in model for search providers to create visual search results, so images can appear in-line in the box’s drop-down list box, which Figure 1 shows, a feature that’s used to great effect by Amazon, among others. And thanks to this new drop-down list, you can easily redirect a search to different providers, moving from, say, Google to Wikipedia with the click of a button. As always, Microsoft lets you keep your default search providers, so if Google is the default before you upgrade, it will still be the default.

On the reliability front, IE tabs and windows now all run in their own processes, so if something in one tab crashes, the crash affects only that one tab. “Crash recovery is great,” Hachamovitch said, “But why not just contain the crash and not end up in that situation in the first place? We think of it as Browser NT,” a comment that should draw more than a few smiles from the enterprise crowd.

The Links toolbar, widely misunderstood by users of previous IE versions, has been revamped and renamed the Favorites toolbar. It’s now used to save RSS feeds and Web Slices, two content types that update frequently and are now more discoverable. Aside from being readily available in the IE 8.0 UI, items in the Favorites toolbar are also bolded when they’ve been updated.

Enterprise Features
Unlike Mozilla Firefox, IE 8.0 is enterprisefriendly. It can be deployed using standard Microsoft products such as Active Directory (AD), Windows Server Update Services (WSUS), or System Center Configuration Manager 2007 (SCCM), and it can be slipstreamed into Windows client and server installation images. A new version of the Internet Explorer Administration Kit (IEAK) provides pre- and post-installation management of the application, including the ability to configure hundreds of new IE 8.0–specific features via over 100 Group Policy settings. You can also manage compatibility issues by using IE 8.0’s new version of the Application Compatibility Toolkit (ACT). And on intranets, IE 8.0 defaults to IE 7.0 rendering mode.

Microsoft will support IE 8.0 with updates for the duration of the life cycle of the OS on which it’s installed. And unlike with other browsers, IE 8.0 updates can be managed and configured centrally using existing Microsoft management technologies such as AD, SCCM, and the like.
