Announcing Internet Explorer Developer Channel


Summary: Go get the new Internet Explorer Developer Channel at devchannel.modern.IE!

Just a few weeks ago, we talked about creating a more open dialog between the IE team and the Web development community. Today we’re excited to announce the release of the Internet Explorer Developer Channel, a fully functioning browser designed to give Web developers and early adopters a sneak peek at the Web platform features we’re working on. The Developer Channel is available for download today for both Windows 8.1 and Windows 7 SP1 customers running Internet Explorer 11.

IE Developer Channel can run alongside and independently of IE11, and has all of the browser features that you love in IE11, as well as the latest platform features we’re working on. As you test drive these features, make sure to give us feedback through @IEDevChat or Connect.

More enhancements to the F12 Developer Tools

In April, we described some of the new capabilities of F12 Developer Tools in IE11 with Windows 8.1 Update, and its focus on providing accurate data in the DOM Explorer and actionable data in the memory and performance tools. IE Developer Channel comes with even more improvements to the F12 developer tools, including:

  • An enhanced debugging experience with event breakpoints that help you get to your event-driven bugs faster.
  • Richer analysis capabilities throughout the Memory and UI Responsiveness profilers, which support further reduction of noise through multi-dimensional timeline filter, while further increasing the semantic value of the data being reported by lighting up performance.measure() based instrumentation and dominator folding.
  • An improved navigation experience that provides more keyboard shortcuts (ctrl+[ and ctrl + ]), as well as new header notifications, which allows you to quickly determine whether any of the profiling tools are running or how many errors your page has.

A complete set of enhancements is available on MSDN here.

Automate your tests with WebDriver

IE Developer Channel also comes with support for the emerging WebDriver standard through which Web developers can write tests to automate Web browsers to test their sites. It’s a programmable remote control for developing complex user scenarios and running them in an automated fashion in your Web site and browser. See how you can setup WebDriver in the IE Developer Channel, and try out this sample WebDriver project.

Use your Xbox controller for Web gaming

Ever felt like using your Xbox controller to game in your browser? IE Developer Channel comes with support of the emerging Gamepad API standard that lets you use JavaScript to add gamepad support to your Web apps and games. Try it out by attaching your Xbox 360 controller and helping the world Escape from XP, play your favorite Atari Arcade games, or try Hover.IE!

IE Developer Channel also improves WebGL performance and adds support for instancing extension, 16-bit textures, GLSL builtin variables, and triangle fans. This release improves our Khronos WebGL Conformance Test 1.0.2 score from 89% to 94%. For more info about these WebGL APIs, go to MSDN here.

The first of many Developer Channel releases

As we work on new features and standards, we will continue to share early code through the IE Developer Channel. You can always go to the DevChannel.Modern.IE page to learn more about the latest features in the IE Developer Channel. All of the new features supported in IE Developer Channel are also listed on Status.Modern.IE, our new portal to communicate our roadmap for interoperable Web platform features.

Internet Explorer Developer Channel features on status.modern.ie

This release of the IE Developer Channel uses a combination of code changes and virtualization to run alongside IE11. This virtualization creates a small performance hit, so we don’t recommend you use this version to measure your site’s performance. We also don’t recommend you install this version in your enterprise environment. For more on known issues, see our list of Frequently Asked Questions.

We look forward to hearing your feedback @IEDevChat or via Connect, to help us move the industry forward and continue to enhance the browser. Also, be sure to join us at our next #AskIE session on Thursday, June 19th @ 10AM-12PM PST.

    Here's what chrome has done right – even though chrome is on version 26 (or whatever,) it hides this from the user. By very contrast, IE continues to push the updating responsibility to the users. This coupled with users/institutions that does not possess the skill or ability to upgrade IE, makes it impossible to enjoy the upgrades.

    I agree with Michael in regards to the icon. Please give us something slightly different. Maybe switch up the blue and the yellow instead? That'd still maintain the branding for IE, yet be distinct enough so that you know at a quick glance that something is different.

On Windows 9 smartphones and tablets, improve and try to compete with Apple Safari mobile browser. On Windows 9 desktop and laptop computers, just like I suggest you to offer desktop mode on Windows 9 desktop and laptop computers and tile mode only on Windows 9 tablets and smartphones, I suggest you to make more updates and changes to Desktop UI IE 12 with major UI changes and improvements to Desktop UI IE 12 for Windows 9 asap including newer social media sharing capabilities.

    Microsoft, for the fckn love of god, either beef up your IE team considerably or just fork Blink. Just do it. Swallow your pride. Leave IE engine for legacy enterprise apps, and with IE13 just fork Blink. At this moment IE is hurting the web, so for the greater good – just kill it.

    Love it or hate it IE has come a long way , and even though I doubt I'm the first to say this I'm going to say it anyway , IE needs a rebranding , desperately .

    REBRANDING + INDEPENDAT UPDATBILITY + SUCCESS OF IE + BING ; because we all know the only reason ie hasn't been discontinued is to promote MS online services , not that it's a bad reason though 😉

    Thank you so much for the improvements and bringing new features to F12 Dev Tools.

    Please consider this: The time spent on HTML/CSS by devs/designers is more than compared to any other tool in F12DT (second most significant tool would be Console, which needs 1: syntax highlighting, 2: auto-complete in addition to suggestion box).

    For HTML/CSS, here are some basic features which many of us are used to and urge IE to prioritize:

    Color picker and Ruler tools

    //connect.microsoft.com/IE/feedback/details/798021

    Cannot select and paste multiple CSS rules and properties.

    //connect.microsoft.com/IE/feedback/details/791981

    "Copy elements with styles" ignores @font-face.

    //connect.microsoft.com/IE/feedback/details/797447

    Quick glance at elements' dimensions (height, width, border-radius) and images preview.

    //connect.microsoft.com/IE/feedback/details/798009

    Visual Studio 2012+ like priority color palette.

    //connect.microsoft.com/IE/feedback/details/798046

    Ability to toggle element states.

    //connect.microsoft.com/IE/feedback/details/800084

    Media query overrides for debugging layout.

    //connect.microsoft.com/IE/feedback/details/801923

    Ability to quick edit start-tag and its corresponding end-tag.

    //connect.microsoft.com/IE/feedback/details/805145

    Change numeric values using keyboard up/down keys.

    //connect.microsoft.com/IE/feedback/details/805163

    Disconnected from browser frame

    //connect.microsoft.com/IE/feedback/details/811024

    Thanks again!

    @wiensha – The HTML5Test isn't a representive test, it checks if a browser responds on something, not if it's actualy supported. Also, it checks and gives points for non-standards. The IE team should focus on adding things that actualy matter instead of the – sometimes very silly – things benchmarks and tests like HTML5Test give points for. This isn't a competition to be the best at benchmarks, it's a competition about bringing the best user experience and standard support. And believe it or not, Chrome can learn a lot about the later one from the recent IE versions.

    It's like the boy that cried wolf. I remember IE8. It was going to be different  – put the crimes of previous years behind it. Likewise, every subsequent release. It never is. Past performance is the best predictor of future success, ergo there is a lot of cynicism out there. Also, admittedly IE11 has, on paper, a decent feature-set, but what about the versions for mobile devices from where 50% of traffic for many sites now comes?

    Have the Dev Tools been fixed to not render the style attribute on elements with what (MICROSOFT) wants to display but rather what I specify?

    when I set:

    style="border:3px dashed red;">

    Oh and why on earth in the Layout panel do input fields of type hidden show padding and border sizes?… they don't render thus should all be 0 or grayed out (or both)!

    If you want to improve the situation and reduce costs, fork WebKit.  I'm tired of supporting decisions made in 1999 to outsource browser development with no standards oversight during the process.

    Just fork WebKit already and WATCH THE WORLD EMBRACE YOU WITH OPEN ARMS.  Or keep chasing the dragon that IE standards will be universally embraced.

    I am glad that IE 12 will work with Windows 7 as well as Windows 8, as I and many others are still with Windows 7.

    When IE 11 was in development, the first version worked with Windows 7 and 8, later development versions only worked with Windows.

    But the final version works with Windows 7 and 8.

    @Webkit Won – You know, the issue here is more Webkit/Blink and you coding specific for this render engine instead of using the HTML and CSS and any other standards. If you follow the standards well, IE won't give you any problems. To many developers however take Webkit-specific code for being standards, and that's a bad situation. Just moving all browsers to Webkit/Blink isn't going to solve the issue, and will make the situation only worse. I'm a web developer, and the hard time developing web software is now because of Chromium, not IE. Lot's of issues have been reported to projects I work on that only appear in Webkit-based software while IE and Firefox are perfectly capable or handling it right… Beside, 17% indeed isn't a marketshare where you can say that they "won".

    Webkit is awful. In the past 2 years I've spent months fixing sites to look fine in Chrome – they ALWAYS have some weird error in either the rendering or the javascript. Yeah, they have a high HTML5test score, but those numbers don't correspond for the quality of implementation. Which is bad enough on desktop, but ten times worse on mobile – and again ten times worse when you consider the highly fragmented Android platforms.

    By comparison, code I write usually works perfect in Firefox and IE. The only time extra work arises is if a certain version needs to be targeted, such as when the client opens the site on an outdated version of Firefox or IE.

    And this is without going into the chrome-specific bugs, like the complete and utter joke that was font rendering under Windows, until they finally decided to use Direct2D in one of the recent updates. It took Google 2-3 years to get Google Fonts to work on Google Chrome.

    Chrome is the new IE6.

    You guys must deal with that amount of crap internally and expose a simple api which just works and is working on many versions without changing a thing.

    What about javascript based addons ? Why do I need to implement an extension to IE in C++ in 2014 ? Why is developing it in C# is also messed up ?

    Maybe using 2D transforms in combination with border-radius and overflow:hidden clipping, which leads to rendering corruption due to broken hardware-accelerated rendering in Webkit/Blink. Or before that; trying to use border-radius in combination with <img> elements.

    Or maybe trying to use position:fixed elements, which suffer rendering corruption when not hacked onto their own compositor layer to placate Webkit/Blink. etc. etc.

    It looks that they may use webDriver or physical devices, but essentially they take the page source from every device and analyse it to identify any platform incompatibilities and issues. In the end you get the report and step-by-step instructions to fix issues that cover the following areas:

    – cross platform compatibility

    – browser and server side performance

    – usability

    In 2011, Windows XP was already not supported, even though it had three more years of extended support and a very high market share (close to 50%, I believe) at the time.

    Given that, why would you expect an operating system with only 2.7% market share (that has less than three years of extended support left as well) to be supported?

    @Chris – Yeah right, let Google get the web all for themselves, because we haven't had such a situation before. What could possibly go wrong?* Well, Googles browser is a pain to develop for, it's worse then IE is, much worse. Vendorprefixes in Chrome are the standard, you have to write your code twice, just to get it working in Chrome – and any Chromium browser for the matter – if you want to use some of the newer abbilities in browsers.

    Beside, Internet Explorer is a great browser, the developer tools are great – even better in this developer release – and it supports HTML5 and CSS3 and any other bleeding edge non-standard-that-will-become-a-standard-some-day very well, in some cases much better then Chrome (follows the standard correctly instead of own inprentation). Also, isn't it Chrome that allows everyone to view your passwords with a couple of clicks? Yes. Yes it is.

    * Remember IE6? It's the exact same situation as the one you want here.

    @Yannick,

    MS IE has vendor prefixes just like everyone else. Microsoft even created their own non-standard version of version of Javascript again called Typescript. Of course you would know that if you had to actually develop websites and web apps with MS IE in mind. Chrome has the best support for HTML5 standards of any browser. IE isn't even second or third in that regard. Both FF and Safari beat IE in HTML5 standards support. It's not even up for a debate. That's just the fact of the matter. Performance wise MS IE is the slowest. The developer tools are terrible. I use them every day. They are the worst of any vendors tools. There are no extensions so developers can get around perceived deficiencies if they need to as it relates to tooling like FF. I prefer Chrome FF and Safari's developer tools to IE. Chrome because they are the easiest to use to get real work accomplished. Safari dev tools I like because it has support for debugging mobile browsers.

    @Yannick: Vista's 2.9% desktop share is, depending on the source, still 2-3x more than all Linux distros combined together, and almost half of MacOS's share. So yes, people still very much use it. Hell, I still use Vista on my laptop. Anything you can do on 7, you can do on Vista, too. I know, I know, sounds unbelievable, but after 2 Service Packs and a Platform Update, it really isn't bad. Same stuff as 7, just stuck with IE9.

    Sure would love IE12 released for Vista and for 2008 (non-r2), it would definitely help with standards compliance and possibly security. But like, not gonna hold my breath. Pity, because people either have to use massively outdated IE9, or – ugh – Firefox or Chrome.

    And it was an even bigger mistake to let XP users down, especially with a huge market share like that. The thing is, user's won't upgrade their operating system or computer just because they can't have Microsoft's latest browser. They will rely on Firefox or Chrome instead, and they will keep it that way when they upgrade their operating system or get a new computer. And Microsoft won't get that market share back. After all, why should I rely on a browser that could stop getting updates every time Microsoft wants me to jump ship on their new OS?

  108. Anonymous says:

    @jfjuneau

    People who refuse to upgrade from a 12 year old OS are not very high on the list of Microsoft customers.  The other browsers still support XP because they want to steal market share.  If it wasn't for that they would never have bothered because properly supporting XP costs a lot of development time that could be spent making the browsers better.  So you are actually complaining that Microsoft chose technological progress over a very minor drop in market share of something that they give away for free.

  110. NumbStill says:

    @Yannick –

    Monoclature is bad, of course. But let us get the facts straight here.

    – Chrome does not introduce new vendor prefixes anymore as a matter of principle ever since they forked WebKit to create Blink (April, 2013). While the Chromium WebRTC team did introduce a few minor prefixed fields (for statistics and IPv6), it was inadvertent and it will not happen in the future.

    – Chrome is trying to reduce the already prefixed features and introduce their standard variants. It has already unprefixed some features (WebAudio, for example) and more unprefixed features are indeed on the plate (CSS animations, full screen API) or even shipping soon (CSS transforms). This is a partial list – groups.google.com/…/forum$3Aintent$20(unprefix$20OR$20unprefixed)%7Csort:date

    – I agree that Internet Explorer tends to have a more complete and standardized implementation than Chrome in some features, but not in all of them. They also have vastly incomplete features.

    – Internet Explorer itself introduced (and still does, apparently) a lot of vendor prefixed features in the last three major releases. Just look at the CSS properties and values that were added for touch related stuff. There are numerous properties (over ten, over twenty maybe) – a lot of them have no specification, or even a draft.

    – The Developer Tools of Internet Explorer are very, very slow. The whole browser is very slow in terms of at least user interface (clicking on buttons, startup time, switching tabs, opening new tabs). Now, that might be a subjective issue, due to slow computers and stuff – but when you compare the feature between, for example, Chrome and Internet Explorer, Internet Explorer is way, way slower on the same machine. I do not think you can argue with that. Loading an uncompressed jQuery and debugging it was so painfully slow (I have not tried it with 11, I admit). I took about two minutes to start debugging. In Chrome, it was (and still is) instant. I am not talking about really slow machines. Core2 Duo 2GHz is not the slowest computer.

    – Chrome no longer lets you view the password with a single click, it shows the system login now.

  111. NumbStill says:

    @Chris –

    – And Google has created Dart, so what? They can create any language they want – no current stable browser currently supports any language other than JavaScript (note that VBScript is no longer supported).

    – Chrome (and the rest of the bunch) does indeed implement a lot of features. Some of them are indeed somewhat incomplete or buggy, though. When Internet Explorer finally implements a feature, they do tend to have a complete implementation, as I mentioned above. Not always, of course. But, yes, Internet Explorer has a lot to catch up – but they do catch up eventually. Major (or minor) releases are now more frequent, so they will catch up faster incrementally.

    @jfjuneau –

    I did not state that I agree with their view, I just stated the facts in order to make you realize Window Vista is not on their radar at all, considering the Windows XP situation and that it is not surprising at all (and you should not expect any Windows Vista oriented release, because you will surely be disappointed).

    @Prior Semblance –

    "minor drop" is an understatement. They stopped supporting it in Internet Explorer 9 – it had almost 50% market share.

    It takes virtually no effort to make a program work on XP as well as on newer Windowses. It all comes down to using the right compiler, and the right framework, that on their turn act as a catching net for API's that XP doesn't have. That aside, don't forget that XP is a very capable OS that can in theory run almost any Windows program out there. It's just that some vendors choose the anal approach and simply make their programs refuse to run when the OS version is 5.1 or earlier, regardless of anything.

    Great news! Looking forward to have better tooling, especially around javascript debugging! Keep it up!

    @Chris,

    first of all:

    TypeScript is NOT to be run in the browser

    TypeScript is a SUPERSET of JavaScript, which is based on drafts for EcmaScript 6

    TypeScript "2.0" (no version number assigned yet), has the goal of aligning the language even more to EcmaScript 6.

    TypeScript has a compiler which "compiles" it into PLAIN JavaScript based on which version of JavaScript support you wish for

    is your complaints about TypeScript 100% irrelevant to IE? YES..

    IE

    @All the "Chrome is better" /"Chrome won" / "Give it up already" / "Chrome has better scores in tests!"…

    First of all, before even talking about HTML5 support, people need to understand what "HTML5" is and more importantly, what HTML5 is not!

    HTML5 is NOT a standard. (currently a "Candidate Recommendation" which is a proposed standard, which is somewhat well defined)

    HTML5 is often used a wide "umbrella" for all things web vNext, instead of actually looking into the W3C drafts!

    All the "HTML5 tests" I have ever seen, does not only test for "HTML5" features, but also much more which is either still in early drafts (experimental) or not even near HTML5. WebSockets support ( http://www.youtube.com/watch ) is probably one of the best examples of this alongside WebGL, video and audio codec support.

    @Martijn

    You need to catch up on security features of Windows introduced with and ever since Windows Vista, if you really believe it takes "virtually no effort" to port an application to Windows XP 🙂

  114. NumbStill says:

    @Martijn –

    This is so not true. A lot of GPU related stuff, updated drivers, DirectWrite and more are pretty much bound to Windows 7 and later. Internet Explorer makes heavy use of hardware acceleration, GPU. Security features such as ASLR and more do not exist in Windows XP. Internet Explorer has no network stack of its own, it depends on the operating system, so many features that bring on speed can simply not be implemented in Windows XP without a great architectural change in the browser that a soon to be (or already is) obsolete operating system does not justify.

    Every software has its own characteristics and a modern browser uses a lot of the new features that modern operating systems provide. Unless you are a browser engineer, or specifically, an Internet Explorer engineer – stating that it is virtually no effort is meaningless.

  115. NumbStill says:

    @Ken

    – Like you wrote, HTML5 is indeed an umbrella term for the latest additions (completely standardized or on their way to be standardized) and when talking about that umbrella term, Internet Explorer is indeed behind. The semantics do not really matter here, the features do – Internet Explorer implements significantly less features than other modern browsers. That is a fact.

    Also, note that W3C itself is purposefully relating these technologies to HTML5. It is a known buzz word (and it works, it seems). Do not blame others for using that umbrella term if officials use it in the exact same way.

    – Regarding WebSocket, the protocol itself is not HTML at all, right, but the API is part of WHATWG HTML – http://www.whatwg.org/…/network.html

    – I completely agree with you regarding the "virtually no effort" contradiction. 🙂 See my comment above.

    From IE 9 things have been great. Sites load faster and ad free in IE WITHOUT any add ons. If you cant browse safely, ad free without add ons and efficiently on IE then you clearly have no clue about browsers or how to work. In fact it is trivial to be ad free globally WITHOUT ANY ADD ONS for everything, from Win 8 apps to non-MS desktop apps that have ads in applications.

    Then again what am I saying people like to punish themselves and use crappy stuff ignorantly, just look at all the losers staying on XP when Win7 / Win8 is better in all ways. Ignorance is what allows bad technology to grow, all you have to do is read the comments by pro-Apple, pro-Chrome, pro-WinXP and pro-Linux to understand what I mean.

    @Prior Semblance – I don't complain about Microsoft not providing their latest browser to their older operating systems, if they don't mind loosing market share in the browser market for the sake of "technological progress" that's their choice. And it's not like we don't have any alternatives, we use Google Chrome at work. It's really easy to manage and deploy using GPOs in a Windows network.

    Also I don't expect any Vista related release either for any Microsoft product. But if Microsoft don't support IE12 on Vista now, why would they release IE13/14/15 on Windows 7 in 4-5 years? They could just say that the new version depends on Metro technology only present in Windows 8/9 and for that reason Windows 7 is stuck at IE12. Meanwhile in Firefox and Chrome land, everything is business as usual and you get all major release as soon as it's available.

    Really I have nothing against Internet Explorer, it's a really great web browser and it's user interface is way better than Chrome if you ask me. But I have to make decisions concerning the development of our internal business apps, and since 2 years we decided to support only Chrome and Firefox since it's the only 2 browsers that we believe in the future will give us peace of mind no matter what OS we will be using on our network. Internet Explorer could come back to the top, but Microsoft will have to change the way they support it. Who knows, they released Office for iOS, maybe we will see IE for Android in the near future…

    Color picker – We’re working on a color picker and hope to have it shipped in the next update.

    Ruler tool – We removed the old ruler tool from F12 as it didn’t have much use and we didn’t have enough time to rebuild it. The tool is on our backlog and I’ve added your comment about prioritizing it higher. No plan on when we’d get to it though.

    Multi select CSS – We’re working on this one we just added multi select to our breakpoint window but not to the CSS panes. Yet.

    @font-face – We have a general issue in the tool that we don’t handle referenced values like font-face and keyframes. It’s something high on our backlog and we hope that we’ll be able to get to it soon.

    Color pallete – We’ll have a color pallete as part of the color picker

    Element states – Today we support :hover and :visited what other states were you interested in?

    Media query toggling – We have work on our backlog to improve the experience for debugging different layouts.

    Numeric up/down – Toda we have the up/down arrows increment the value by +/- and shift + +/- will change the value by 10. We’re looking at adding shortcuts for fractions (0.1 increments). Does that cover your needs?

    Disconntect from browser frame – We’re adding the ctrl+click to follow links in the debugger. The F5 and key propogation issue is something we’re looking at but are someone hampered by the input model for IE.

    The F12 tools should show shorthand properties in CSS rules.

    > Multi select CSS – We’re working on this one we just added multi select to our breakpoint window but not to the CSS panes. Yet.

    The multi-select in breakpoint windows is not as convenient as the we have in Firebug/Chrome. In other words, we need click-and-drag selection for CSS in addition to press-and-hold-Ctrl-and click. In CSS window, its mostly the adjacent rules/declarations devs are interested to copy. Please note that it is like a text selection; meaning click-and-drag selection in CSS window should work across the rules. See i58.tinypic.com/ors4gp.png

    > Element states – Today we support :hover and :visited what other states were you interested in?

    :link, :active and :focus.

    > Numeric up/down – Toda we have the up/down arrows increment the value by +/- and shift + +/- will change the value by 10. We’re looking at adding shortcuts for fractions (0.1 increments). Does that cover your needs?

    Besides fractional increment, please consider increment/decrement in DOM viewer. For instance; in most front-end frameworks, they have grid structures with column spans ("col-6" of twitter bootstrap or "larger-6" of zurb foundation). Please provide increment/decrement of those too. In addition to that, h1-h7 tags are also a good candidate of such a shortcut except it has a fixed range. The idea is to let user see the real-time change without needing to: change — press Enter — change — press Enter.

    > Media query toggling – We have work on our backlog to improve the experience for debugging different layouts.
