Hello The_Boojum,

Your system details show that you have the latest Adobe Flash installed : it shows as "Shockwave Flash 31.0.r0" in Options => Add-ons => Plugins ......

When you go to Windows Control Panel, you should see it listed there as "Flash".

Not listed as Flash in the windows control panel. Also it installs perfectly in Edge and Chrome just not in FF. The things I want to view work in Edge and Chrome but not in FF so it is clearly NOT installed and has a different function to that of Shockwave.

What page are you using for your testing? For example: https://helpx.adobe.com/flash-player.html

In case you haven't used the "click to play" activation feature before, see: Why do I have to click to activate plugins?

Web browsers like Firefox and SeaMonkey uses a NPAPI version of Flash Player Plugin while Chrome/Chromium uses PPAPI and Edge has its own version and the old Internet Explorer uses a ActiveX version.

Shockwave Flash is the old name for Flash Player from Adobe.

Shockwave (for director) Player is a completely different Plugin and not really used by current web browsers anymore except maybe IE?

The (NPAPI) Flash Player Plugins are not installed into Firefox but are installed on your OS whether on Windows, Mac, or Linux. To see where your Flash Player Plugin that Firefox is making use of is located type about:plugins in the Location (address) bar.
