I have the latest Silverlight 5 plugin installed; also the latest Safari browser (6.5.1) under Mac OSX 10.8.5.
Silverlight fails, showing a small box with the msg. "Plugin failure" - whenever I try to play video (for example from NetFlix) - 100% of the time when using the Safari browser.
This has been going on for weeks - I've tried reinstalling Silverlight, Safari, and rebooting, etc.
However, when using Firefox (28.0) there is no such error and everything plays fine.
I hope Microsoft is not going to simply blame Safari and Apple.
Has anyone else experienced (or solved) this problem?
