Microsoft Silverlight will reach the end of support on October 12, 2021. Silverlight development framework is currently only supported on Internet Explorer 10 and Internet Explorer 11, with support for Internet Explorer 10 ending on January 31, 2020. There is no longer support for Chrome, Firefox, or any browser using the Mac operating system. I am using Firefox ESR 52.1.0 on a MacBook. I was on Mac OS High Sierra and Silverlight was working on Safari until I installed Safari 12. At that point Firefox ESR 52.1.0 still ran Silverlight. I along with other users of a company Silverlight application have updated to Mac OS Mojave.
Bottom line you were mislead. Silverlight was a proprietary plugin by Microsoft. Microsoft stopped development of Silverlight a year ago. Like many Microsoft proprietary frame works they abandoned it after it failed to gain traction in the market.
Safari dropped support for Silverlight (and all classic plugins) some time ago. You might try using Chrome or Firefox instead. They may still support Silverlight. But read the Microsoft article link provided. The end is near and Silverlight is now effectively a Windows only framework. You may want to consider installing Windows on your Mac using the Bootcamp app. It requires a licensed copy of Windows. You can also use a virtual environment like Parallels to install Windows on your Mac.
