Silverlight Installed Not Running

Alright, do these steps in this order (even if you already did one of these steps, just try again):

Mar 19, 2020  Silverlight Not Working On My Mac I am able to download Silverlight onto my Mac, but I cannot get it to work. It says it downloads successfully, but when I got to watch say Netflix or use it for one of my online lectures it says that I haven't downloaded it.

Microsoft Silverlight Plugin Netflix

1. Use http://ninite.com/firefox-flash-silverlight/ninite.exe to make sure Firefox, Flash and Silverlight are fully up to date. Ensure that Firefox is fully closed before you run this program. (It might be useful to download this, restart your computer, then run it)
2. After Installing, restart your PC Again.
3. Open Firefox, type about:addons into your address bar, press enter. Go to plugins. Do Flash or Silverlight show up there? You may need to enable them.
4. If not, Reset Firefox. Refresh Firefox - reset add-ons and settings
