I recently installed windows 10 on my PC and just found out i can't watch anything on firefox with the flash player plug-in, it doesnt crash but instead of a video, the screen is just green but there's sound, and when trying it with other browsers, it works fine. I've attached an image to highlight this...

The green screen is an old problem with the Flash plugin. As a workaround, you can disable the plugin from using hardware acceleration:

On a site with Flash, right-click the media and choose Settings, then the first mini-tab and uncheck the box to use hardware acceleration.

Does that help in Windows 10?

By the way, your Question Details > More System Details shows two versions of Flash, 15.x and 18.x. To locate and remove the old version, you can type or paste about:plugins in the address bar, then use Find (Ctrl+f) to look for NPSWF and find the physical location of the old DLL file. Usually it's safe to remove but if you're nervous, renaming it with a .OLD extension should hide it from Firefox.
