Facebook video calling for Firefox for Windows, in Wine

[BenWiley4000]

I am trying to use Facebook video calling, and I am running Ubuntu 12.04, which clearly is not supported by Facebook video calling. I installed Firefox 12 for Windows using Wine, and it works perfectly. I installed Adobe Flash player for Windows using Wine, and it works perfectly in Firefox for Windows. But I tried installing the Facebook video chat plugin, and when the setup tries to download the installer from the Internet, it crashes. Google Chrome for Windows has a similar installer and I think it has the same problem. Is there a way to circumvent this?

Thanks
