Firefox is not recognizing MS Silverlight is installed on my Win 7 PC. When going to a website that requires Silverlight, a pop up asks me to install it...but it is already installed (v5.1.50906.0). Just started recently. Restarted PC, updated Firefox, etc..

What version of version are you running   ?
The regular release of Firefox 52+ only allows one plugin, which is Flash. The Extended Support Release (ESR) of Firefox 52 + will still run Java, Silverlight, etc. You can download the ESR Firefox version here :

https://www.mozilla.org/firefox/organizations/all/

When you get to the ESR installer list, you'll notice at least two different downloads for Windows: • Windows installer is the standard version for Windows that runs on both 32-bit and 64-bit Windows Vista through 10 (and 32-bit XP), the best choice for most users. • Windows 64-bit installer ONLY runs the Flash and Silverlight plugins, so that is what you're looking for.
