"The above site doesn't use Adobe Flash, but Microsoft Silverlight. Probably you have Moonlight installed, and you think you are seeing a Flash video, but you actually see a Silverlight video."
That may be so, but the site prompts for Flash install on first run inside a fresh install, and then prompts for Silverlight/Moonlight plugin install after that.
When all those steps are completed (auto-installing the 32-bit flash and then manually selecting the X64 Moonlight plugin) viewing a video and then right-clicking properties in the video window locks up Firefox. Replace the 32-bit Flash with the 64-bit Flash and doing right-click works correctly.
The bottom line is that the 64-bit Flash plugin functions as it is supposed to and the 32-bit one doesn't.
