    TLS and SSL in the real world

    • 48 Comments
    Quite a bit has been written about the Secure Sockets Layer (SSL) protocol and its successor Transport Layer Security (TLS), so I won't cover the protocols in detail here. The following are good references if you want to get a quick refresher. Microsoft KB article describing the SSL Handshake Wikipedia Overview of TLS Happily, a majority of web users now know to look for the lock icon and the HTTPS in the address line to identify when their connection is secure. Unfortunately, relatively...

    A Note about the DHTML Editing Control in IE7+

    • 73 Comments
    Hi, I’m B. Ashok, the Product Unit Manager for Web Development Tools – we have our own team blog ( http://blogs.msdn.com/webdevtools ), but I wanted to post over here to discuss a change my team has made which has an effect on users of IE7+ in Windows Vista. Specifically, we are removing the DHTML Editing Control from the Windows Vista product. The DHTML Editing Control shipped in Windows XP and Windows 2003 Server, in a file called dhtmled.ocx. This file contained two flavors of the control:...

    IE8 Security Part II: ActiveX Improvements

    • 65 Comments
    Hi, I’m Matt Crowley, Program Manager for Extensibility with Internet Explorer. The team was very excited to be at the RSA security conference last month discussing the security features of Internet Explorer 8 Beta 1. In this, the second part of the IE8 Security blog series, I describe the ActiveX improvements in IE8 and summarize the existing ActiveX-related security features carried over from earlier browser versions. Per-User (Non-Admin) ActiveX Running IE8 in Windows Vista, a standard user...

    HTML5, Hardware Accelerated: First IE9 Platform Preview Available for Developers

    • 163 Comments
    When we started looking deeply at HTML5, we saw that it will enable a new class of applications. These applications will stress the browser runtime and underlying hardware in ways today’s websites don’t. We quickly realized that doing HTML5 right – our intent from the start – is more about designing our browser’s subsystems around what these new applications will need than it is about a particular set of features. From the beginning, we approached IE9 with the goal of enabling professional-grade...

    Announcing Internet Explorer Feedback

    • 168 Comments
    Many customers have asked us about having a better way to enter IE bugs. It is asked "Why don't you have Bugzilla like Firefox or other groups do?" We haven't always had a good answer except it is something that the IE team has never done before. After much discussion on the team, we've decided that people are right and that we should have a public way for people to give us feedback or make product suggestions. We wanted to build a system that is searchable and can benefit from the active community...

    HTML5, Native: Third IE9 Platform Preview Available for Developers

    • 215 Comments
    As developers experiment and begin the transition from writing today’s websites to building HTML5 applications, they will test the limits of browsers. For example, the huge difference between hardware accelerated HTML5 video and plain HTML5 video support in a browser was clear in the demo we showed at MIX . Because some browsers run on many different operating systems, there can be a tendency to use a “least common denominator” approach to implementing HTML5. By using more of...

    What’s New for CSS in Beta 2 Preview?

    • 227 Comments
    We have heard all your feedback asking us for full CSS compliance. With the now public available Beta 2 Preview build on XP, we get a big step closer to this goal. Chris talked about our priorities for IE7 before , but I want to give more detail on our work with CSS. We had 3 objectives, in priority: Fix some really nasty bugs posted on sites like positioniseverything.net Revise parts of our existing CSS implementation to be true to the spec Add the most-requested new CSS functionality...

    Engineering POV: IE6

    • 262 Comments
    The topic of site support for IE6 has had a lot of discussion on the web recently as a result of a post on the Digg blog . Why would anyone run an eight-year old browser? Should sites continue to support it? What more can anyone do to get IE6 users to upgrade? For technology enthusiasts, this topic seems simple. Enthusiasts install new (often unfinished or “beta”) software all the time. Scores of posts on this site and others describe specific benefits of upgrading. As a browser supplier, we want...

    ECMAScript 3 and Beyond

    • 101 Comments
    There have been a number of blog posts recently about JavaScript developments, e.g. Gabriele Renzi’s " ECMAScript 4, the fourth system syndrome ". For ECMAScript, we here on the IE team certainly believe that thoughtful evolution is the right way to go; as I've frequently spoken about publicly, compatibility with the current web ecosystem - not "breaking the Web" - is something we take very seriously. In our opinion, a revolution in ECMAScript would be best done with an entirely new language, so...

    How IE8 Determines Document Mode

    • 56 Comments
    This post describes how IE8 determines what Document Mode such as Quirks or Standards Modes to use for rendering websites. This topic is important for site developers and consumers. It’s related to the Compatibility View List that we recently updated . This list is down by over 1000 websites, from over 3100 to just over 2000, since IE8 released last March. As we work with site developers and standards bodies, we’re excited to see the sites that need to be on the Compatibility View...

    Session Cookies, sessionStorage, and IE8 or “How can I log into two webmail accounts at the same time?”

    • 37 Comments
    For Internet Explorer 8, we’ve made browser session handling a lot simpler. For instance, say you want to have two Hotmail windows open, each logged into a different account. Simply click the New Session item on the File menu, and a new browser window will open. The new browser window will not share session cookies with the original browser window, so you can log into Hotmail (and most web applications) as a different user. For command line junkies, you can run iexplore.exe with the -nomerge parameter...

    IE9 and Privacy: Introducing Tracking Protection

    • 72 Comments
    The feedback and conversation on IE9’s Platform Previews and Beta to date from many different communities has made the IE9 development process, and product, substantially better than previous releases. The discussions around hardware-accelerated HTML5 and same markup with the developer community, for example, have informed many changes to the product. Thank you for using it and providing feedback. In general, we’ve focused this blog on engineering issues. In this post, still continuing...

He is the developer currently working on our IE7 print experience. Since he works out of Microsoft's offices in Reading, England, we are much better now at printing “tomatoes”. Without further ado: Today, there is a well known problem with printing from Internet Explorer where the layout of the page sometimes...

    Hello! Just wanted to give you a quick update that we’ve dropped two new VPC images that you can use with the free copy of Virtual PC 2007 . The first is a refresh of the Windows XP SP2 + IE6 image . A few people were encountering a non-genuine Windows warning from the Windows Genuine Advantage (WGA) Notification Tool. We did not install the WGA Notification tool on the image this time around. As we’ve mentioned in previous blog posts , these images have had their product keys deactivated, thus...

    Browser Power Consumption—Leading the Industry with Internet Explorer 9

    • 146 Comments
    Power consumption is an important consideration in building a modern browser and one objective of Internet Explorer 9 is to responsibly lead the industry in power requirements. The more efficiently a browser uses power the longer the battery will last in a mobile device, the lower the electricity costs, and the smaller the environment impact. While power might seem like a minor concern, with nearly two billion people now using the Internet the worldwide implications of browser power consumption are...

    IE in Windows XP SP2

    • 174 Comments
    Hi, I’m Tony Chor, the Group Program Manager for the Internet Explorer team. As you may know, we’ve been working hard on IE for Windows XP Service Pack 2, and we signed off on it last week. You can get a very detailed description of the changes on MSDN. (This is lovingly referred to internally as the Book of Springboard – Springboard was the codename for XP SP2.) However, I thought I’d give a high level description of the kinds of changes we made and why. First, as with any project, we set our goals...

With this update, the curated Compatibility View (CV) list blocks Flash content in the small number...

    Caching Improvements in Internet Explorer 9

    • 33 Comments
    The network plays a crucial role in the overall performance of a web browser. The best way to improve network performance is to minimize the volume of network traffic by using HTTP compression and taking advantage of the browser cache. We’ve made a tremendous number of improvements to the way that Internet Explorer 9 caches content to ensure that as many resources as possible are loaded from the cache. This post describes those improvements which are now available in the third IE9 Platform...

    URLs in Internet Explorer 7

    • 98 Comments
    Internet Explorer 7 includes a new URL handling architecture known internally as CURI. The new optimized URI functions provide more secure and consistent parsing of URIs to reduce attack surface and mitigate the threat of malicious URIs. When designing our security strategy for IE7 , malicious URIs were near the top of the list because secure handling of URIs throughout IE is critical to the security of the system. Hence, a major architectural investment was made in CURI for IE7. Unlike most...
