The Silverlight plug-in is compatible with all major browsers like Mozilla Firefox and Safari . Once installed, it allows you to view content created with Silverlight, and this is the rub. Whatever the merits of the technology itself (given the few demos available on the Microsoft website , it seems attractive), Silverlight is a little late when Flash already monopolizes the web, including video sharing sites like YouTube or DailyMotion .
