The latest version of Microsoft's browser is fast, lean and means business.
Throw away what you think you know about Internet Explorer -- because the just-released IE9 will turn it all on its ear. Think IE is sluggish? Think again, because according to SunSpider tests, it rivals or beats the speed demons Chrome and Opera. Believe that IE sports a tired-looking interface? No longer --- it now has the same type of stripped-down look that Chrome originated, and that the latest version of Firefox uses as well.
IE 9 (available only for Vista and Windows 7) also introduces other goodies, such as HTML 5 support, Windows 7 integration, a double-duty address bar and more. It's clearly Microsoft's best shot at stopping the erosion of its market share by rivals Firefox and Chrome.
Moving to a clean interface
Microsoft takes a page from Google Chrome with its design for IE9 -- it's simple and clean, putting as much focus as possible on Web content and not on the browser itself.
All unneeded buttons and controls have been eliminated, and tabs are now at the top of the browser. (For a bit of simple eye candy, the top and the sides of IE9 are transparent.) The arrangement works. Web pages take center stage, with very little to distract you, and IE9 taking up as much real estate as possible. There's not even a search box; as with Chrome, the address bar does double-duty as a search box.
Three small icons on the upper-right corner of the screen give you access to IE9's options and feature a Home button, a Favorites button for managing bookmarks and a Tools button shaped like a gear. The Tools button leads you to most of the browser's other features and options, such as security, privacy, add-ons customizing search and so on.
There's another new feature to the IE9 interface as well. When you open a new tab, it displays thumbnails of pages you frequently visit. At the bottom of each thumbnail is a bar that shows how frequently you visit each page. The longer the bar, the more you've visited the page. And there are some very useful other things you can do from this page as well, including reopening your last browsing session, reopening tabs you've closed during this browsing session, and getting recommendations for sites you might want to visit, based on the sites you frequently visit. You can also launch an anonymous browsing session, which IE terms "InPrivate Browsing."
IE9: The new speed demon?
Among the loudest complaints against previous versions of Internet Explorer was its lack of speed. In a world in which graphics-heavy Web pages get heavier every year, videos are becoming normal elements and Web-based apps are replacing desktop-based applications, this sluggishness could have become a fatal flaw.
IE9 beat all the others. It took an average 280 milliseconds (ms) to complete the tests, followed by Opera 11.01 at 308.8 ms, Chrome 10.0.648 at 316.7 ms, Firefox 4 Release Candidate at 319.1 ms and Safari 5.0.4 at 410.2 ms.
As a practical matter, there's not much difference in these tests between the top four performers. It's not going to be noticeable by most surfers. But in previous tests I ran, Internet Explorer 8 took between five and six times the amount of time to complete the SunSpider tests as its next slowest rival Firefox, making this an astonishing speed improvement. And the fact remains: On this test, Internet Explorer beat all rivals.
It's an open question, though, as to whether Internet Explorer's hardware-accelerated GPU handling of processing-intensive work is superior to other browsers. The upcoming Firefox 4 also uses hardware acceleration, and Microsoft and Firefox have been trading fire over which browser is superior in that aspect. We'll have to wait until a set of agreed-upon benchmarks emerge for measuring that capability before judging.
Keeping up with standard
Past versions of Internet Explorer have been criticized for not adhering to Web standards, something that Microsoft has fixed in Internet Explorer 9. Microsoft now has an Internet Explorer Test Drive page to demonstrate embedded videos and other features. However, the
As a practical matter, this is moot at this point, because you'll have to search long and hard to find Web pages that use the
To test overall HTML 5 compatibility, I ran IE9 and other browsers through the HTML5 test page. IE9 scored at the bottom with 130 out of 400, while Firefox 4 Release Candidate scored 240, Opera scored a 234, Chrome rated 288, and Safari came in at 228. Of course, given how little HTML 5 is used at this point, it's not clear how relevant these numbers are at the moment. But Microsoft needs to do some work to prepare Internet Explorer for HTML 5 when it becomes widely used. At this point, it's the least compliant browser, at least according to the HTML test page.
As for normal Web browsing, IE9 displayed nearly every page I visited properly, with a few exceptions. On my iGoogle home page, it would not render the Web-based version of Google Talk. And on the Computerworld blogs, it didn't show any of the comments that readers made. I was able to solve the problem with Computerworld blog by clicking on IE9's Compatibility View button, which displays the page as thought it were being rendered by Internet Explorer 8. In subsequent visits to that page, IE9 remembered to display it using the earlier version of the browser. However, Compatibility View didn't solve the problem with rendering Google Talk.
A better address bar
With IE9, the address bar now does double-duty as an address bar and a search box. (To highlight this, Microsoft refers to it as One Box.) As you type your search, the browser looks at your History, Favorites and Feeds, and displays matches. In that way, you can more quickly find a site or do a search by selecting a choice and pressing Enter. You can, of course, also type in your entire search term and press Enter to search the Web using your default search engine.
(On my Vista test machines, the address bar didn't launch searches when I typed in text. To fix the problem, I clicked the tools icon in the upper-right part of the screen and selected Internet Options --> General, clicked Settings in the Search section, checked the box next to "Search in the address bar," then clicked OK. On my other test machine, I didn't need to do this; however, this may have been an anomaly.)
You can also have your keystrokes sent to your search provider (such as Bing or Google), so that the provider can see what you're typing and suggest possible matches. IE9 turns that behavior off by default for privacy reasons, but you can turn it back on if you want.
IE9 lets you easily route your searches to other search providers rather than your default one. As you type in a search term, icons of other search providers appear underneath the list of matches. Simply click any icon to launch the search using that provider. That's all well and good. But when you do this, you're actually changing your default search provider to the alternate provider. So even if you only want to search Wikipedia once for a particular search, choosing its icon means that all subsequent searches will be done through Wikipedia as well, until you change it back -- a feature that can be very troublesome.
Making friends with Windows 7
Microsoft has tweaked IE9 for Windows 7, giving the browser some capabilities not available when it runs in Windows Vista. The most noticeable is that you can pin a Web site to the taskbar by dragging its URL to the taskbar. The site's icon then appears in the taskbar; to visit the site, click the icon. When you get to the site this way, the site will essentially "brand" IE9 -- the forward and back buttons will use the colors of the pinned site, and the Web site's icon will appear in the upper left of the browser. IE9 does this on its own; no development on the part of the site owner is required.
Web developers can use the Windows 7 Jump List) to add site navigation and additional features (such as music controls) to the pinned icon.
These features, while potentially very useful, may not turn out to be as helpful in actual practice. Adding features to the Jump List requires programming on the part of the site owner. In the past, Microsoft has added special features such as Web Slices that required site owners to do development work in order to take advantage of them -- and they rarely did so. Given that even Microsoft.com hasn't done any programming to take advantage of Jump Lists, it's not clear that this will become widely used.
Pinning a site can also prove to be somewhat annoying, because when you launch a site in this way, it launches in its own browser, and not as a tab in an already open browser. That means each pinned site will run in its own browser instance, making it confusing to switch among them.
IE9 also uses another Windows 7 feature, Windows Snap. Tear away a tab away from IE9, and drag it to the side of the screen, and it resizes the tab, and places it in its own window, to fill half the screen.
Performance Advisor and Notification Bar
Browser add-ons can slow a browser's performance, and IE9 includes a nifty tool called the Performance Advisor to help you track down ones that might be particularly problematic. When you launch IE9, the Performance Advisor looks to see whether any add-ons might slow down the browser, and then opens the Notification Bar at the bottom of the screen.
If you click "Disable add-ons" you'll see a screen that shows name of the add-ons, their manufacturers and an estimate of how much extra time they each take when you're launching your browser, opening a new tab or navigating to a Web site. Even Microsoft's own add-ons are included. You then have the option of disabling any to speed up browsing. This is a great tool for letting you decide whether the capabilities of an add-on are worth the browsing delay it extracts.
The Notification Bar offers other info as well. It tells you, for example, if you're visiting a Web page that includes both secure and non-secure content, such as an online store that uses an HTTPS/SSL secure connection, but also displays ads, images or scripts from a non-HTTPS server. At that point, the Notification Bar warns you that IE9 is displaying only secure content, and gives you the option of displaying both types of content by clicking the "Show all content" button. This is useful but potentially annoying, because this notification appears every time you visit the Web site; you have to click the button each time.
