    Google Bypassing User Privacy Settings

    When the IE team heard that Google had bypassed user privacy settings on Safari, we asked ourselves a simple question: is Google circumventing the privacy preferences of Internet Explorer users too? We’ve discovered the answer is yes: Google is employing similar methods to get around the default privacy protections in IE and track IE users with cookies. Below we spell out in more detail what we’ve discovered, as well as recommendations to IE users on how to protect their privacy from...

    Sub-pixel Rendering and the CSS Object Model

    With Windows 8, you have an unprecedented choice of devices for browsing the Web, from large desktop screens to small slates. In order to accommodate this range of devices, the browser must be able to scale and layout the Web at many different screen sizes and dimensions. We've previously blogged about some of the features in IE that support these scenarios. Sub-pixel positioning (of text and layout) is one of the core platform technologies which enable Web pages to look beautiful and consistent...

    CORS for XHR in IE10

    The fourth platform of IE10 simplifies building cross-site scenarios that work consistently across browsers by supporting Cross-Origin Resource Sharing (CORS) for XMLHttpRequest (XHR) . CORS for XHR makes sharing data across sites simple and flexible. In the most basic scenario CORS enables creating data sources accessible from any site, and with a few small tweaks you can choose to constrain allowed sites, support data modification, and even allow authentication. Most importantly CORS keeps existing...

    High performance HTML5 content in Metro-style Apps

    Metro style apps in Windows 8 have all the performance benefits of IE10 when showing Web content. In Metro style apps, Web content is always JIT compiled and hardware-accelerated. Other platforms do not provide the same level of performance in apps. For example, Cocoa apps on iOS offer significantly worse JavaScript performance (via the UIWebView control) than the same content running in Safari. These Cocoa apps do not enjoy JIT compilation, and these apps cannot show and use Web content the same...

    CSS3 3D Transforms in IE10

    CSS3 features make it easier to build rich and immersive Web experiences. A recent post described how Web developers add personality to their sites with CSS3 Transitions and Animations. CSS3 3D Transforms add another dimension (literally) for developers to enhance their sites. For example, the Windows 8 Metro style Start page uses subtle 3D transforms to highlight pressed tiles, as shown below. Internet Explorer 10 tile shown not pressed (left) and pressed (right) Adding a...
