I am an avid fan of Opera, and have been for a number of years. Despite its bad rap, it is a very solidly built browser that has phenomenal standards support.
A some of the sites that I use have started moving from Flash (or custom plugins) to Silverlight. One of the most notable is NetFlix Instant Watch. In some cases, Silverlight works perfectly in Opera. However, in cases such as with Netflix Instant Watch, opera has some trouble loading Silverlight.
I believe this is simply because of how the Silverlight plugin is configured. With past versions (Silverlight 2, mostly with Silverlight 3) some clever User javascript would solve the problem in Opera. However, I have not been able to get Silverlight 4 to work in most cases, and there are still issues with Silverlight 3.
Does anyone know how to get the Microsoft Silverlight plugins working smoothly in Opera? I am not afraid of user javascript, addons, or other tweaks. I would love to get Silverlight working consistently and smoothly across the board in Opera.
