    • 14 Comments
    Our commitment to same markup includes script along with HTML, CSS, SVG, and the other markup that developers use to build the web. To make same markup real, the community needs a set of official tests to assess how interoperable and standards-compliant different browsers are with the latest version of JavaScript, “ECMAScript Fifth Edition” (fondly known as ES5). As we mentioned in a recent blog post , Ecma International (the standards body behind JavaScript) is working through a process...

    Declaring Security

    • 11 Comments
    Recently, a number of people have asked me what I think about Mozilla’s Content Security Policy draft spec. Back in January, I went on record as being someone who thinks that CSP is a good idea. CSP is a mechanism for declarative security , whereby a site communicates its intent and leaves it up to the user-agent to determine how to enforce it. There are a number of benefits to declarative security mechanisms: Reduced compatibility risks. Because sites must opt-in and declare what, if...

    Add-ons, Installation Experiences, and User Consent

    • 19 Comments
    As discussed in previous blog posts, add-ons can have a material impact on browser performance . IE measures the performance of add-ons so that users can make informed decisions about them. It is important to understand how add-ons arrive on a user’s system to begin with because browser performance is so important to site developers and to consumers. The notification and control that users have around the add-on installation process is equally important because add-ons can also have an impact...

    IE9’s Assistive Technology Interface Enhancements

    • 6 Comments
    IE9 introduces improvements to the interfaces used by assistive technologies (ATs) to enhance the accessibility of Internet Explorer. These changes relate to IE9’s switch to hardware-accelerated rendering of HTML content. Previously, some accessibility tools depended on IE’s GDI-based rendering to scrape information from Web sites. Since IE9 has no GDI-based rendering, these features do not work with IE9. Anticipating this problem, Microsoft has worked closely with assistive technology vendors (ATVs...
