    Native HTML5: First IE10 Platform Preview Available for Download

    IE10 Platform Preview 1, available for download today is the first step in delivering the next wave of progress in native HTML5 support.

    Hang Resistance in IE9

    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. We also perform...

    Getting the Most from IE9 and Your GPU

    Over the past year, Internet Explorer 9 went from a technology platform preview to final release for millions of users. Before IE9 beta, our opt-in telemetry data showed IE9 running on a relatively small number of high-end GPUs. Within two weeks after beta release, IE9 was running on nearly every kind of GPU in the world—from expensive and fast desktop GPUs to power-sipping netbook GPUs. In this post we talk about our approach to ensuring IE9 is using the GPU across a broad range of PCs, and what...

    Add-ons and IE Reliability

    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...

To highlight the quality and performance differences in hardware acceleration, let's look closely at the Paintball test drive, released with IE 10 Platform Preview 1 . Paintball...

    Thoughts on when to use Canvas and SVG

    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 ). These technologies can be used to address a range of graphic scenarios on the modern Web. With a lot of excitement around Canvas, there has been a tendency to ignore SVG, which, in many cases, is the better choice. Here I offer some thoughts on when to choose Canvas...
