After reading the other threads related to this issue, I did some research and found the following: 

 First - The environment Firefox v. 47  x64 on Windows 7

Regardless if using Flash 21 or flash 18, once installed you can open the browser and it works although a bit slow. once you close and re-open Firefox, it gives the "Context3D..." error.

Now, if you downgrade Firefox to version 46.x it works reliably with flash 21 and flash 18. Therefore, it is obvious that there is a problem with version 47 of Firefox (at least the x64 build).

The Flash stage3d feature that provides CONTEXT3D doesn't work with the Shockwave Flash plugin used in 64 bit Firefox version. You will have to install the 32 bit Firefox version is you need to use Flash stage3d features.

You can find the full version of the current Firefox release (47.0) in all languages and all operating systems here:
