Introducing IE11: The Best Way to Experience the Web on Modern Touch Devices

As part of today’s Windows 8.1 Preview, Internet Explorer 11 (IE11) Preview is now also available.  Fast, fluid and perfect for touch, IE11 continues our vision of providing the best Web experience across the full range of Windows devices and screen sizes – an experience where sites and apps work flawlessly together. IE11 offers better touch performance, faster page load times, a continuous browsing experience across your Windows devices, and completely rebuilt F12 developer tools.

Performance matters to everyone who browses the Web. The way to judge performance is how responsive browser and device are, especially to touch. On today’s devices, touch is the new fast. We built IE to be fast, responsive, and battery efficient, especially with touch.

Immersive Browsing

IE11 delivers a fast, fluid experience, using as many tabs as you want, and side-by-side browsing so you can use your favorite sites and Windows Store apps together. IE11 puts your sites first, delivering the best Web on Windows across the full range of Windows devices and screen sizes, that’s equally great for touch, mouse, and keyboard.

And because you expect to be able to continue the browsing you do from one Windows device to the next, IE11 adds support for accessing tabs open across your devices, kept in sync through the cloud with SkyDrive. As you move between your Windows devices, your open tabs, favorites, history, user names/passwords, and more are always up to date and under your control.

Touch Optimized

Touch performance continues to be an area of focus, building on the work we did in IE10. Improvements you will notice in IE11 on Windows 8.1:

Best browser touch responsiveness and battery life on Windows devices: IE11 produces “stick to your finger” touch responsiveness by using the GPU to process gestures such as panning, zooming, and swiping. GPU-offloaded image decoding enhances battery life and keeps the CPU processing dynamic page content. IE11 makes browsing more responsive by prioritizing work and by pre-fetching content in the background.

Touch optimized address bar: Get to your most frequently used sites quickly, always fresh and up to date with the browsing you do across all your devices. Typing is faster with site suggestions, including direct links to site sections, Bing search suggestions, and suggested Windows Store apps. You can even get instant answers for weather and stock prices from the address bar.

As many tabs as you want: Up to 100 tabs per window, with independent tab suspension for efficient use of memory and battery, and faster switching with tabs that are there when you need them, out of your way when you don’t. Responding to feedback, IE11 has a new option to always show your tabs and address bar for faster, easier access with the mouse or finger.

More beautiful, touchable favorites: Full support for Favorite sites with folders and custom tile pictures that are more personal and always stays in sync with the desktop and across all your Windows 8.1 PCs.

Navigation built for touch: Touch optimized UI with swipe for forward and back gestures, with page prediction and pre-rendering, make going to next page and going back instant. A more touchable Web with touch hover menu support.

Your sites first: The most important part of the screen is available for your sites with a single, unified interface with tabs and address bar at the bottom optimized for fast access and touch.

Enabling the Next Generation of Sites and Apps

We optimized the IE11 browsing engine for real-world sites to download and display fast and be highly responsive to touch. Developers can build next generation experiences with professional-quality Web video, and hyper-fast 2D and 3D Web technologies that make the most of the underlying hardware. IE11 supports real world standards and compatibility, and new developer tools enable developers to build high-performance Web experiences on Windows devices.

Some of the key ways that Windows 8.1 provides the best stage for the real-world Web while enabling new 3D, gaming, and media experiences:

Create live site tiles in the Windows 8.1 Start Screen. With Windows 8.1, your pinned sites can now be alive with activity, pulling data from your Web site.

Modern Web development is easier. IE11 supports the latest standards and frameworks actively used by Web developers. Brand new F12 tools in IE enable iterative, visual debugging and tuning of Web sites. Modern.ie enables cross-browser testing, no matter where you choose to develop.

Hardware-accelerated 3D Web graphics. Interoperable WebGL experiences run on all devices, taking advantage of GPU acceleration. IE11 scans for unsafe WebGL content and implements a software-based renderer to complement the GPU. With Windows, graphics subsystem failures are not fatal, and WebGL continues to run. With IE11, your 3D experiences can access device orientation to create new interaction opportunities for immersive Web content.

The existing Web continues to work – even better: IE11 is interoperable with existing sites, which just run faster and look better in IE. Of course, intranet sites and apps continue to run in IE11, which supports Compatibility View.

Enable professional-quality video experiences on the Web. IE11 supports plugin-free HTML5 video with the latest standards for closed captioning, streaming that adapts to available network bandwidth, and rights management - so all your video content can be as good as the professionals. Power-efficient video streaming in Windows 8.1 extends battery life for Web video. If you install the Windows 8.1 Release Preview, you can visit Netflix to watch your favorite movies and TV shows using HTML5 without the need to install any plugins.

Build Windows apps that deliver world class Web content. Embed live Web sites into your Windows apps, taking advantage of hardware acceleration to integrate Web and app content and provide fluid touch interactions.

Best Web Experience with Apps and Sites Together

IE11 and Windows 8.1 enables developers and consumers to have the best of both worlds – amazing next generation applications that are optimized for Windows devices, and first class experience of Web sites together with apps that is great across the full range of Windows PCs. You can check out more examples on the IE Test Drive site.

Please install the Windows 8.1 Preview from the Windows Store to try IE11. You can find a full list of new functionality available to developers in the IE11 Preview Developer Guide here. We look forward to reading your feedback on Connect and continuing to engage with the developer community.

    So does the new dev tools let you still toggle into previous versions of IE, or do we need to run VMs for that now? I heard that drag and drop works for touch now. Does this mean that you can move images in a WYSIWYG editor with a touch now? I've previously used JavaScript methods to add support for this in TinyMCE using touch events and IE10's pointer events. If images are now draggable and the JavaScript is unnecessary I wouldn't want to add those events. How would you recommend testing for this? I really don't want to do browser detection to add the events.

    @Dean Hachamovitch [MSFT] 1- Will IE11 be able to run on Windows 7? Will people have to buy Windows 8 or Windows 8.1 in order to use IE11 ?? These are important questions. 2- Sandeep Singhal [MSFT] says that IE11 support border-image but there are no tests at IE test center. Will those tests be uploaded soon? 3- All test results at IE test center show results for Firefox 16, Chrome 22, Opera 12.02 and Safari 5.1.7 ... but those browser versions are 6months-12months old. And so, those test results are not recent. Will the test results be updated with latest browser versions? 4- Will all the tests at IE test center be submitted at CSSWG for inclusions into respective test suites? AFAIK, none of them have been submitted, reviewed and approved yet. Gérard Talbot

    @GT There's nothing dishonest about this benchmark from what I can tell. Google has been reluctant to add support for the setImediate standard for the last two years. We shimmed setImmediate into Chrome for our frameworks and there's an easy workaround. There's been lots of debate by lots of smart people and pretty much everyone agrees setImmediate is fantastic except for Google who believe polyfills that only work in Chrome are reasonable. setImmediate is now in node and most viable frameworks. I'm sick and tired of Google's s**t.

    I know IE will support webm, ogg, and other formats if the codecs are installed... is there a compelling reason why these codecs aren't just installed with Windows 8.1?  It would sure reduce a lot of complaints if most media type "just worked" without having to go and install special codec packs, or special apps that install the codecs for you.

    webm and ogg are proprietary formats. webm is a 100% google owned and controlled format with patent issues and something similar for ogg which is 100% owned and controlled by xiph. . Opus however is an open standard developed within and owned by standardization organisation IETF for which all contributing major companies have promised free licensing of their IP rights.   If anything Microsoft should include Opus support in IE11.

    The benchmark uses setImediate(). It is part of the Efficient Script Yielding draft specification at W3C It is only considered inappropriate by parties that do not support it I presume. If sites judge chrome on arbitrary support of W3C drafts or even non W3C drafts (webrtc) than why should Microsoft not use W3C drafts in their benchmarks. However even without using the setimmediate script element the benchmark runs much better and smoother on IE11 compared to for instance chrome.

    Supporting setImmediate() coming from a Working Draft (" a work in progress and may change without any notices. "; a Working Draft is not a Candidate Release) does not prove performance and speed superiority; it just proves that IE11 currently supports setImmediate(). This very interesting article news.en.softonic.com/microsofts-browser-benchmark-cheats-gives-ie-11-speed-crown claims that " After adjusting the test to give all browser the same smallest timeout value [in other words, the same test conditions], Internet Explorer 11 actually came out about 30% slower than Chrome. Even Firefox managed to be quicker than IE 11. In reality, IE 11 is in 3rd place with Opera and Safari following. " Disclaimer: the article does not identify the versions of browsers (Chrome, Firefox, Opera, Safari). Gérard Talbot

    @Jan: ignoring now the discussion whether setImmediate should exist or not (in the way it's currently specified) - the test should emulate it in the best possible way available on the browser, and that's not setTimeout. It's like page testing some new feature of Canvas, and when that particular canvas method was missing, it would switch from canvas to abs.positioned square divs (instead of emulating it by drawing pixels or what's appropriate). Would that make sense? What exactly would it prove?

    hi, i've got a few user experience enhancements for you - free of charge, because IE11 made really good improvement make fwo fingers swipe to the left/right: switch between tabs make hold (the link) and swipe to the right: open the link in a new tab these are the most used navigation commands that are the most "under represented" in touch browsers. a big amount of actual user experience actually depends on them and it's a good opportunity to jump ahead of others again, just like you did on the touch OS level with swipe from the left side of the screen (to jump between apps) and full screen app content.

    O, and another really important one. Make opening links in new tabs easier! the drop-down menu in ie10 was bad enough (but somewhat normal) but ie11 is even worst, because the distance between hold and the next tap is much longer. to get to the point - opening links in a new tab is so popular option that should it should be available in a single gesture. you should't have to perform a gesture (hold) and than LOOK somewhere (to find the button) and perform another gesture (tap). it should be as easy as: hold the link (until the hover menu appears) and swipe to the right. imagine you are at the search results page and you want to open all of them in new tabs. if you use a mouse it is as easy as middle-clicking on all the links - it can be done in a moment. now imagine how much time you would need if you wanted to do this with touch by using your hover menu. a nightmare ... so what i'm saying is leave the hover menu because it's useful for other not that much used commands, but enable a new single gesture to open the link in a new tab. maybe can do it by holding and swiping go the right. and maybe enable holding and swiping to the left or up to search the word in the search engine, and then we have a winner ;)

It doesn't seem like a lot of work to add that. Are there any plans to add it?

    Have you ensured that the new F12 Developer Tools are accessible to users who are blind and are using screen readers such as Jaws or NVDA? I am a blind Web developer and I use the IE tools extensively because all other browsers' developer tools are not really accessible to screen readers. IE was the only browser whose tools were accessible to me because they were using standard Windows controls and not fancy HTML5 "what you see is not what you get" widgets. I mean, all other browsers are trying to simulate the richeess of the Windows UI controls through HTML5, which might look visually correct and which might behave to the mouse as expected, but they are inpossible to navigate through and read their contents easily using the keyboard. And please, bare in mind that adding a few keyboard shortcuts here and there is not enough. Can I use the cursors to read through the code for example, or is the cursor just simulated via a div highghlight. I hope not.
