If you use the link in the following article, can you download Silverlight: [[Use the Silverlight plugin to play audio and video]]. (It does seem to run in Firefox 18.0.2 on Windows 7 (64-bit) for me.) SkyDrive is a cloud storage service from Microsoft. It is commonly used for picture sharing by Windows Live Hotmail users. There is a Windows application to integrate SkyDrive into your system which you can download here: [http://windows.microsoft.com/en-US/skydrive/download]. That probably runs independently of your browsers, communicating with Microsoft directly. Regarding viewing photo albums on Microsoft services, we had a thread a while back about compatibility issues but I can't recall seeing anything recently. If you are having problems with that, could you describe what you're seeing (or not seeing) in more detail?
