    Staying in Control of Your Default Search Provider

    • 7 Comments
    One of our guiding principles in Internet Explorer is to keep users in control of their browser. This applies to settings like the home page , enabled add-ons , and the default search provider. Sometimes, 3rd party software changes the consumer’s default search provider without their consent . Consumers may be surprised to see search results from an unfamiliar Web site and may not know how to change back to their previous default search provider. As we work with developers to ensure that they use...

    Galactic: Building a 3D Solar System with HTML5

    • 41 Comments
    Last November, we released the Galactic test drive alongside IE9 Platform Preview 7. This test drive is a 3D simulation of our solar system and depicts planets orbiting around the sun. You can press the “V” key to toggle between a close up view centered on the sun and a zoomed out view showing more of the entire scene. When I set out to build Galactic, I knew that I wanted to use HTML5 Canvas to render my scene in 3D, but I wasn’t quite sure how to go about it. After skimming a handful of 3D math...

    Deleting “Flash Cookies” Made Easier

    • 11 Comments
    If you follow Web Privacy issues, you’ve probably heard about “ Flash Cookies .” In the same manner that Web developers can use HTTP Cookies to store data, developers who use Adobe Flash Player on their Web site can use Flash Cookies to store data. Internet Explorer users are accustomed to deleting their cookies via Delete Browsing History . However, because Flash is an add-on and not part of standard HTML content, browsers have not been able to delete Flash cookies the same way they delete HTTP...

    ActiveX Filtering for Developers

    Add-ons and IE Reliability

    • 34 Comments
    Third-party software (such as add-ons ) causes many of the crashes you experience in IE. From an analysis of the error reports submitted during IE9 Beta, third-party code accounts for around 70% of all the crashes in IE. While we work hard to improve IE9’s reliability in-house, it’s equally important to ensure that the add-on ecosystem is compatible with IE9. This is a challenge faced by other browser vendors as well. Throughout the IE9 development cycle, we addressed the top...

    Thoughts on when to use Canvas and SVG

    • 26 Comments
    HTML5 Canvas and SVG are two exciting graphics features introduced in IE9. Both were covered in sessions at last week’s MIX11 conference in Las Vegas (see Deep Dive Into HTML5 <canvas> and Modernizing Your Website: SVG Meets HTML5 ).

    Hang Resistance in IE9

    • 54 Comments
    IE9 is the most reliable browser available today in terms of hang resistance. In this post on IE reliability, we show how we engineered IE9’s hang resistance so that an unresponsive tab no longer affects the rest of the browser, similar to how IE is resistant to a crashing tab with Tab Isolation . We highlight new user experiences that help you recover from hangs caused by Web pages, long- running scripts or slow add-ons so that you can browse continuously without interruption.
