Firefox3 and Silverlight misbehaving on your site? Read this

So this is, admittedly, a little outside of what I usually talk about, but wanted to share with you, my dedicated reader(s):

In order to support Firefox 3, websites built using the Silverlight 1.0 Sivlerlight.js file must upgrade that file to the latest version. In addition to supporting Firefox 3, the latest version of the file also adds several new features including the ability to automatically refresh the browser once the user installs Silverlight. You can learn about all of the new features in the readme file.

If you have already updated your website to use the Silverlight 2 Beta 2 Silverlight.js file or you instantiate Silverlight using the ASP.Net Silverlight control then no further action is needed. Otherwise, to obtain the latest version of Silverlight.js please visit the Silverlight.js MSDN Code Gallery Web site:

http://code.msdn.microsoft.com/silverlightjs

For most pages, the upgrade process will only require that you replace the current Silverlight.js file with the new version. However, the latest version of Silverlight.js removes several deprecated members from the file’s object model:

o Silverlight.ua

o Silverlight.available

o Silverlight.detectUserAgent

o Silverlight.supportedUserAgent

If your website uses any of these members then you can find workarounds in the readme file associated with this release.
