  • Prototype implementation of Gazelle Web Browser

    Researchers Helen J. Wang, Chris Grier, Alexander Moshchuk, Samuel T. King, Piali Choudhury and Herman Venter of Microsoft Research published a paper on The Multi-Principal OS Construction of the Gazelle Web Browser.

    They see a need for a new kind of web browsers as the way people use the web and web browsers has changed over the past years.

    Web browsers originated as applications that people used to view static web sites sequentially. As web sites evolved into dynamic web applications composing content from various web sites, browsers have become multi-principal operating environments with resources shared among mutually distrusting web site. Nevertheless, no existing browsers, including new architectures like IE 8, Google Chrome, and OP, have a multi-principal operating system construction that gives a browser-based OS the exclusive control to manage the protection of all system resources among web site principals.

    Their solution is a web browser with its own kernel for a mini operating system named Gazelle.

    … we introduce Gazelle, a secure web browser constructed as a multi-principal OS. Gazelle’s Browser Kernel is an operating system that exclusively manages resource protection and sharing across web site principals. This construction exposes intricate design issues that no previous work has identified, such as legacy protection of cross-origin script source, and cross-principal, cross-process display and events protection. We elaborate on these issues and provide comprehensive solutions.

    Gazelle might not only what we might see as Internet Explorer 9 some time in the future but Gazelle might be a solution for existing browsers.

    Our prototype implementation and evaluation experience indicates that it is realistic to turn an existing browser into a multi-principal OS that yields significantly stronger security and robustness with acceptable performance and backward compatibility.

  • IE 6 Death – March 2009

    iedeathmarch2009badge IE 6 Death   March 2009

    German it news site Golem just put up an article with the title IE 6 shall die (roughly translated). Basically they name all the initiatives that want the IE 6 to be wiped out. Some of the highlights are:

    This is all about the campaign to rid the WWW of Internet Explorer 6 that has devastated web developers and held back the evolution of everything that blocks the tubes for far too long. This can not go on any longer! Off with its head!

    Source: IE6: Do NOT want!

    It’s time to put a deadline on dropping IE6, and I say that time is now, and the deadline should be soon… say like, March 2009. That’s roughly a little more than 6 months.

    Source: We *Like* Our Internet With a Side of Revolution

    We totally agree with the call and support the extinction of the IE 6!

  • How-To: Faster requests with Mozilla Firefox

    firefox 3 150x150 How To: Faster requests with Mozilla Firefox If after upgrading your Mozilla Firefox installation websites suddenly load painfully slow we might have a solution. By default in newer Firefox installation IPv6 is enabled. At the time being IPv6 requests tend to be slower than IPv4 requests to the DNS system.

    So disable IPv6 in Firefox as follows:

    1. Type ‘about:config’ in the Firefox URL bar
    2. Accept the warning
    3. Type ‘ipv6′ in the Firefox URL bar
    4. An entry named ‘network.dns.disableIPv6′ appears
    5. Double click this entry to set the value to true.

    Now Firefox will use the IPv4 protocol for name resolution.

  • User Agent Switcher as Mozilla Firefox Addon

    user agent switcher User Agent Switcher as Mozilla Firefox Addon If you do web development or cannot access a page because it asks for a certain user agent you might want to test how a site reacts to a user agent string other than which your default browser sends a little add-on called User Agent Switcher comes in handy.

    If you are using Mozilla’s Firefox as a user agent most likely you are almost aware of its capability to add features through its add-ons. One of the available add-ons is the User Agent Switcher by Chris Pederick. With the add-on which is available for free (donations are welcome!) you can switch the identifier your browser sends on the fly. That way you can pretend you are surfing a site with a mobile user agent if you are still using your regular desktop browser.
