Alright, you can all breathe a collective sigh of relief as I am actually posting a blog entry. The delayed posting I think is worth it: today we are releasing a new Firefox plug-in for WMP! We’ve been tracking the issues in the forums about WMP showing some odd aspect ratio issues, as well as other bugs under Firefox, and we decided to tackle the problem and write a new plug-in to get this working again. Apologies to all for how long it took and the relative quietness we’ve had on this front – we’ve been heads-down getting Vista shipped and then directly afterwards we started working on this plug-in.

There is an existing Netscape plug-in out there, but we recommend that people use our new plug-in when developing web sites that use the WMP OCX. In a nutshell, here’s what we did with the new one:

  • New robust design that addresses all of the known issues with the old plug-in
  • WMP will now work in Firefox in Windows Vista
  • Support for the WMP OCX scripting interfaces

The plug-in has been scoped to support a subset of the 6.4 design time parameters, so existing sites that want to use the new plug-in may need to update some of their HTML tags. If you use the plug-ins new MIME type though, you can take advantage of fuller design time parameter support, based on 9.0 interfaces. We will have the MSDN documentation updated to reflect the supported tags/elements in the near future. In the meantime, if you want to start using the new plug-in, you can force your sites to use it by using the new application/x-ms-wmp MIME type.

Feel free to leave any feedback on the plug-in here, or contact me with further questions.
