    Performance: Profiling how different web sites use browser subsystems

    • 17 Comments
    When we first showed IE9 at the Professional Developers Conference last fall , we discussed how real world browser performance involves many different subsystems. Different websites use these subsystems in different ways, and to build a fast real world browser you have to start by understanding these overall patterns. This post provides an inside look at how these subsystems impact the performance of five real world websites. We use Internet Explorer 8 for this analysis, and as IE9 approaches we...

    • 17 Comments
    I’m Markellos Diorinos, and I am a product manager with the Internet Explorer team. Yesterday I read a story in the Wall St. Journal about how some small businesses, such as the featured Aunt Joy, will receive a lump of coal this Christmas, as they are unable to get the new EV SSL Certificates. Kelvin and Rob have previously discussed EV Certificates, but I wanted to share some of my thoughts with you. Just like regular SSL certificates, EV SSL certificates will only be used when sensitive information...

    • 17 Comments
    Hi, I’m B. Ashok, the Product Unit Manager for Web Development Tools . As mentioned in my earlier post last summer, we have removed the DHTML Editing Control from Windows Vista as part of making the operating system more secure. One application that used the DHTML Editing Control in the past was OWA (Outlook Web Access). We have issued a required update to both Exchange 2000 and 2003 that enables OWA support for IE7 in Windows Vista. However if your server does not have this update applied, you...

    IE7 Dialog Sizes - A Quick Update

    • 17 Comments
    This is just a follow up to my recent post about dialog sizing in IE7 . Based on your feedback regarding the minimum dialog height restrictions, my team re-evaluated our position and changed the minimum height from 150 to 100 pixels. We think this change: Reduces application compatibility issues where dialogs were coded to the IE6 minimum height Is more consistent with other browsers’ minimum height providing more consistency for content developers Again, we appreciate your constructive...

    RSS Secure by Design

    • 16 Comments
    One of the reasons we went to Blackhat last month was to show how the Security Development Lifecycle (SDL) has changed the way that Microsoft builds products. I talked about how we’re reducing attack surface with features like ActiveX opt-in, improving code quality and building-in Defense in Depth with Protected Mode . I didn’t get a chance to cover the new RSS feed support but I think the RSS team’s work is a great example for anyone building a new client to handle RSS feeds and a case study in...

    Happy Holidays!

    • 16 Comments
    The information published in this post is now out-of-date. —IEBlog Editor, 20 August 2012 I want to comment on a couple of things before we all disappear for the holidays. As you may have noticed, we have turned on comment moderation due to the copious amounts of blog spam we have gotten lately. This means there will be some delay for us to review the comments and then post the ones that are not spam. I don’t really like doing the comment filtering (it’s more work for us), but given the spam...

    • 16 Comments
    After months of conference calls, the most recent face to face meeting of the SVG Working Group helped us make progress on this web standard.

    HTML5 Video Captioning

    • 16 Comments
    The promise of HTML5 is a Web that works for everyone. Media accessibility through captioning is an important part of that promise and an area that is still emerging through standards work. Using the proposed HTML5 track element , developers can add captioning to HTML5 video by pointing to a caption file that contains a written representation of the dialog or actions in the video. Once the standards for captioning converge, there will be less need for external add-ons to publish accessible video...
