    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...

    Same Markup: Writing Cross-Browser Code

    • 68 Comments
    I recently presented a session at MIX10 covering the topic of cross-browser best practices. The key focus of the session was not on a particular feature, but on how web developers can reliably write code that adapts to cross-browser differences. IE9 reduces these differences and enables developers to use the same markup across browsers. Enabling the same markup means supporting the right features to make the same HTML, JavaScript, and CSS "just work". Yet enabling the same markup on the web is...

    IE7 Virtual PC Image and IE6 Virtual PC Image Refresh

    • 35 Comments
    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...

    Microsoft CSS Vendor Extensions

    • 78 Comments
    As you may know, all browsers have a set of CSS features that are either considered a vendor extension (e.g. - ms-interpolation-mode ), are partial implementations of properties that are fully defined in the CSS specifications, or are implementation of properties that exist in the CSS specifications, but aren’t completely defined. According to the CSS 2.1 Specification, any of the properties that fall under the categories listed previously must have a vendor specific prefix, such as '-ms-' for Microsoft...

    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...

    Follow Up on HTML5 Video in IE9

    • 176 Comments
    Our recent post generated many comments and questions. The discussion of intellectual property rights is complex and invites many different points of view. This is a good opportunity to talk through the certainty and uncertainty relative to our goals for IE9 from Microsoft’s point of view. Developers have consistently conveyed that they want certainty and predictability in the underlying browser platform. We want to deliver a great HTML5 experience in IE9 with great certainty. The goal of certainty...

    Prepare for Automatic Update distribution of IE8

    • 123 Comments
    In January we blogged about our plan to distribute IE8 via Automatic Update/Windows Update (for simplicity, we'll refer to this as Automatic Update for the rest of this blog post). This post provides some additional information about how users and administrators are in control of browser upgrades. Last week, we released IE8 via Automatic Update to users still running pre-release versions of IE8 (Beta 2 or Release Candidate 1). The goal was to make sure users who chose to install IE8 have the latest...

    User Experiences: Evolving the blue “e”

    • 138 Comments
    “IE9 started from the premise that the modern web will deliver HTML5 experiences that feel more like native applications than sites. Building on hardware-accelerated SVG, canvas, video, audio, and text, developers will use the power of the whole PC to achieve great performance. On the modern web, developers will use the same markup across different HTML5 browsers.” – Dean Hachamovitch, Corporate Vice President, Windows Internet Explorer Why start a post on designing the new Windows...

    IE7 Printing: An Experience You Won’t Want To Miss

    • 95 Comments
    In my previous post , I gave a glimpse of what to come in IE7 and printing. Now that the Beta 2 Preview build is publicly available I like to walk you through all the additions we added to printing and print preview. Internal studies showed that printing is the second most used feature after navigation in a browser and traditionally has not seen the respect it deserves. To address this IE7 focuses around 3 experiences: Having a great default print experience Intuitive UI, putting you...

    IE Automatic Component Activation (Changes to IE ActiveX Update)

    • 170 Comments
    Back in April 2006, we made a change to how Internet Explorer handled embedded controls used on some webpages. Some sites required users to “click to activate” before they could interact with the control. Microsoft has now licensed the technologies from Eolas, removing the “click to activate” requirement in Internet Explorer. Because of this, we're removing the “click to activate” behavior from Internet Explorer! It’s important (and cool) to note that this change will require no modifications...

    IE December Security Update – addressing scattered reports of odd browser behavior

    • 105 Comments
    We have received scattered reports of users experiencing odd browser behavior after installing our most recent security update . Some of you have reported opening a browser window that promptly hangs IE, others have reported opening links that render blank, and finally we have reports of multiple windows opening when initiating a browser session. After investigating several of these reports, we have traced these issues to a common source. If a user has ever attempted to run IE7 Beta1 in an unsupported...

    I want to try IE7 for XP already

    • 108 Comments
    Every day, I get lots of email asking for a build of IE7 for XP. If you have an account on the internal Microsoft corporate network, I have a link I can send you. For everyone else, we need a better answer than “We’re hiring; please come join us.” (That said, we’re hiring; please come join us .) We’ll post an updated pre-release build of IE7 for Windows XP publicly – no MSDN membership required – during the first calendar quarter of 2006. We want to make sure that everyone has an opportunity...

    Dude, where’s my intranet zone? (… and more about the changes to IE7 security zones)

    • 40 Comments
    Internet Explorer enforces security rules for websites by grouping them into categories or “security zones”. Today we want to explain the changes to security zones you’ll see in IE7 so we should first clarify what the security rules are in IE6. On the Security tab of Internet Options under the tools menu, you will see the Internet, Intranet, Trusted Sites and Restricted Sites zones. The rules for security zones control how each group of websites is allowed to interact with your computer. If you...

    Improving the CSS 2.1 strict parser for IE 7

    • 120 Comments
    We've already started talking about a few of the CSS changes that are going to be available in IE 7 when we release, but there are a few hanging points that we haven't talked about yet or haven't covered completely. There are 3 specific items I'd like to talk about: Using the root node wild card selector for IE only rules (* HTML) [strict mode only fix] Multi-class selectors as defined by CSS 2.1 (.floral.pastel) [strict mode only fix] Pseudo-element parsing sometimes flags rules as invalid...

    Native JSON in IE8

    • 27 Comments
    As you may have guessed from the title of this post, Internet Explorer 8, as of Beta 2, offers native JSON parsing and serialization. This new native JSON functionality enables Internet Explorer 8 aware AJAX applications to run both faster and safer! What’s JSON? For those of you that are not die hard AJAX developers, allow me to provide a bit of background. JSON is a simple human readable data interchange format often used by AJAX applications when transmitting data between the server and...

    IE8 Security Part VII: ClickJacking Defenses

    • 34 Comments
    As we planned Internet Explorer 8, our security teams analyzed the common attacks in the wild and the trends that suggest where attackers will be focusing their attention next. Over the course of IE8’s development, we’ve also worked closely with those in the security research community to stay on top of new classes of threats. One of the most subtle and interesting web application security vulnerabilities is called Cross Site Request Forgery (CSRF); security researcher Jeremiah Grossman calls CSRF...

    How to make IE open new tabs faster

    • 86 Comments
    Browser add-ons are a great way to enhance the experience and capabilities of your Web browser. Add-ons are loaded by IE when you open a new browser window or tab. This is usually a quick process, but certain add-ons may cause IE to take a longer time than expected. For example, after installing Skype 4.1*, this user (and his father) encountered a slowdown in IE on their computers. Just like most of you, almost everybody on the IE team is tech support for their parents, so improving the user's ability...

    IE7 Installation and Anti-Malware Applications

    • 110 Comments
    A few people have asked why we recommend temporarily disabling anti-virus or anti-spyware applications (which I’ll refer to together as anti-malware) prior to installing IE7, so here’s a little insight to the situation. Along with copying IE7 files to your system, IE7’s setup writes a large number of registry keys. A common way anti-malware applications protect your computer is by preventing writes to certain registry keys used by IE. Any registry key write that fails during setup will cause setup...
